While reasonable efforts have been made in the preparation of this document to assure its accuracy, changes in the product design can be made without reservation and without notification to its users.Dot Hill assumes that the person using these instructions is qualified in the servicing and installation of storage products.Before you begin•Verify that the installation site meets the enclosure’s requirement for:•Space and airflow •Temperature •PowerFor detailed information regarding installationrequirements, see 2322/2332 information within the web-posted R/Evolution 2002 Series Setup Guide (setup guide hereafter).•Considering your system configuration and weightdistribution in the rack or cabinet, determine where you will install each enclosure within the rack or cabinet.•Confirm that you have cables of appropriate type and length (described herein) to connect to hosts and to power outlets.CAUTION: T wo people are needed to lift and move the enclosure. Use care to avoid injury.CAUTION: Electrostatic discharge can damage sensitive components. Be sure you are properly grounded before touching a static-sensitive component or assembly.Required tools•#2 Phillips screwdriver •Standard screwdriver •Antistatic protection devicesController/drive enclosure installation hardware•Controller enclosure•Controller enclosure ear caps (2 per enclosure)•Drive enclosure(s)•Micro-DB9 serial cable (1 per controller module)•Ethernet cables (1 per controller; not included)•Power cords (2 per enclosure)•SAS cables (1 per expansion module)IMPORTANT: Before installing, see the “Installation Checklist” in the web-posted setup guide.1. Install and secure enclosures into the rackUse the R/Evolution Rackmount Bracket Kit Installation instructions provided with your rail kit when installing and securing enclosures into the rack.2. Install hardware optionsInstall any additional disk drives and options. Refer to the installation instructions provided with your option.3. CablingCommon cabling configurations address hosts, switches, controller modules (featuring Internet SCSI (iSCSI) host interface protocol), and expansion modules.Direct connectionThe 2322 and 2332 each support four server connections, two per controller. Fault tolerance and performance requirements determine whether to optimize theconfiguration for high availability or high performance when cabling.Connect the appropriate cable type from the host ports on each controller to the corresponding Ethernet port on each server. Several examples follow.One server/single pathCable required: 1 - Ethernet (CAT5-E minimum)One server/dual pathCables required: 2 - Ethernet (CAT5-E minimum)Two servers/dual pathCables required: 4 - Ethernet (CAT5-E minimum)Switch connectionThe 2322 and 2332 support four switch connections, two per controller. Connect Ethernet cables from controller host ports to switch ports, and from switch ports to hosts. See the web-posted setup guide for details.Two servers/two switchesCables required: 8 - Ethernet (CAT5-E minimum)Connecting remote management hostsThe management host directly manages systems out-of-band over an Ethernet network:1.Connect an Ethernet cable to the network port on each controller.2.Connect the other end of each Ethernet cable to a network accessible by your management host (preferably on the same subnet).Drive enclosure cable requirementsFollow the guidelines and cabling table below when installing SAS cables connecting controller and drive enclosures:•Use R/Evolution or OEM-qualified SAS 4x cables with 3Gb connectors to connect a controller enclosure to drive enclosures as specified below:•Up to three 2122s per 2322/2332 •Up to six 2130s per 2322•Up to seven 2130s per 2332•Y ou may need to order additional or longer cables if you are cabling a fault-tolerant configuration.•Reverse cabling ensures the highest level of fault tolerance, enabling controllers to access remainingdrive enclosures, if a drive enclosure fails.Rear panel rack mounted component locator view2322/2332 Installation© <Copyright>Revision A edition August 2009Printed in <the US>.P/N: 83-00004621-10Revision A August 2009NOTE: Cabling diagrams use simplified graphics and reference the table below.2322 or 2332 single-controller enclosure and one 2130 drive enclosureCable required: 1 per table above2322 or 2332 dual-controller enclosure and one 2122 drive enclosureCables required: 2 per table above2322 or 2332 dual-controller enclosure and multiple 2130 drive enclosuresCables required: 8 per table at left4. Power cordsIMPORTANT: See “Electrical Requirements” in the web-posted setup guide for additional information.AC models1.Turn off all power switches.ing the provided AC power cords, connect each power supply module to one power source in the rack.3.Connect the primary power cords from the rack to separate external power sources.DC models1.Before making any DC connections, shut off the main circuit breaker in the rack.2.Turn off all enclosure power switches.3.Connect a DC power cable to each power supply using the D-shell connector. Use the up arrow on the connector shell to ensure proper positioning.4.Tighten the screws at the top andbottom of the shell, applying a torque between 1.7 N-m (15 lb-in) and 2.3 N-m (20 lb-in), to securely attach the cable to the DC power supply module.5.To complete each required DC connection, secure the other end of each DC power cable to the target DC power source.IMPORTANT: Check the DC cable labels before connecting each cable to its power source. One wire is labeled ground ; the other two are labeled positive and negative .6.Turn on the main circuit breaker to the rack.5. Powering upIMPORTANT: When powering up, make sure to power up the enclosures and servers in proper sequence.Power up sequence:•Drive enclosure(s) first;•Controller enclosure(s) next;•Switches (if applicable), followed by servers (if they are powered down for maintenance).To power on the storage system:1.Press the power switches on the back of each drive enclosure to the On position. Wait several minutes to ensure that all drives have had time to spin up, so that they can be recognized by the controller.2.Press the power switches on the back of the controller enclosure to the On position.6.

The European chemical industry in a worldwide perspective:2009Chapter 1 Profile of the Chemical Industry1.1 World chemicals salesThe European chemical industry can still be portrayed as vibrant and strong. However, worldwide competition is getting fiercer. In 2007, world chemicals sales were estimated at €1820 billion, an increase of 4% compared to last year. With €537 billion, the EU chemical industry is still in a top position, but has lost its first place in the ranking to Asia (including China and Japan), mainly due to the rise of China and India. Taken together, the EU, Asia and NAFTA (North American Free Trade Area) account for almost 90% of the world turnover.1.2 World chemicals sales (cont’d)Developments in the last 10 years show that the EU was the leader in world chemicals sales but has lost ground against Asia. Comparing 2007 to 1997, the contribution of the EU to world chemical sales was reduced by 2.7 percentage points. In fact, Europe’s sales have been growing continuously, but world chemical sales are growing faster. The value of word chemicals sales has increased by 60% in 2007 compared to 1997.1.3 World network of chemicals trade flowsIn 2007, the key trading regions were the EU, Asia (including China and Japan) and NAFTA. The EU was the world's leading exporter and importer of chemicals, accounting for half of global trade. This includes intra EU trade, mainly for reasons of comparison with other regions, as their figures include this trade as well.1.4 Geographic breakdown of EU chemical industry salesGermany is still the largest chemicals producer in Europe, followed by France, Italy and the UK. Together, those four countries generate almost two thirds of the EU’s chemicals sales (€329 billion). Adding the Netherlands, Spain, Belgium and Ireland raises the share to 88% (€475 billion). Poland is the biggest new EU country, representing 2.3% of total EU chemicals sales.1.5 Sectoral breakdown of EU chemical industry salesThe output of the chemical and pharmaceutical industry covers four wide ranges of products: base chemicals, speciality chemicals, pharmaceuticals and consumer chemicals.•Base chemicals cover petrochemicals and derivatives and basic inorganics.They are produced in large volumes, and are sold to the chemical industry itself or to other industries. They represented nearly 45% of total EU chemicals sales in 2007.•Specialty chemicals cover the auxiliaries for industry, paints & inks, crop protection, and dyes and pigments. Specialty chemicals are produced in small volumes but nevertheless represented 17% of total EU chemicals sales in 2007.•Pharmaceuticals represent both basic pharmaceutical products and pharmaceutical preparations. They accounted for 27% of total EU chemicals sales in 2007.•Finally, consumer chemicals are sold to final consumers: soaps and detergents, perfumes and cosmetics. They represented 11% of total EU chemicals sales in 2007.1.6-1.7 EU chemical industry sales structureEU chemicals sales were estimated at €537 billion in 2007. Sales to EU partner countries have more than doubled over the last ten years. The European internal market has had a very positive effect on chemicals. Removing both trade and non-trade barriers inside the EU area has been a key driver for the growth and competitiveness of the EU chemicals industry. The internal market of 495 million consumers is a key factor of competitiveness. With the accession of the ten new Member States the internal market has received an important push. By 2007, nearly half of sales were intra EU (excluding domestic sales). While intra EU sales are rising, the importance of domestic sales is decreasing, accounting only for 28% of EU sales. The traditional domestic preference is becoming a preference for European products. 23% of chemicals sales are exported outside of the EU area. NAFTA, neighbour countries of the EU and Asia are the key markets.1.8 EU chemical industry consumption structureThe chemical industry underpins virtually all sectors of the economy and its strategies impact directly on the downstream users of chemicals.The consumption structure of chemicals by downstream users gives the following picture:•The big industrial customers of chemicals are the metals, mechanical & electrical industries, textiles & clothing, the automotive industry and paper & printing products, accounting together for 25.1% of chemical consumption by downstream users.•30.3% of chemicals consumption is absorbed by end users in private households, government and non-profit organisations, 16.4% goes to services, 6.4% to agriculture, 5.4% to construction, 6.1% to the rest of manufacturing and 10.3% to other industries.1.9 Added value in EU chemicals and other manufacturing sectorsChemicals is the second leading manufacturing sector (after pharmaceuticals) in terms of "value added per employee" in Europe, followed by the “office machinery and computers”, “radio, television and communication”, basic metals”, “automotives” and “pulp and paper”. The chemical industry’s value added per employee is 86% higher than the average of manufacturing sectors.1.10 The EU manufacturing industry: gross operating surplus/ turnoverWith regard to its gross operating profit, chemicals compares favourably to other manufacturing sectors as well. The ratio of gross operating profits to sales is the 7th highest in industry and is well above the manufacturing average.1.11 Contribution of the chemical industry to the EU economyThe chemical industry's contribution to the EU gross domestic product amounts to 1.2%. When pharmaceuticals are added this figure rises to 1.9%. This may seem small at first sight, but should be re-assessed taking into consideration both the shrinking contribution of industry as a whole to GDP in advanced economies (-1.5% over the last 5 years in the EU) along with a rise in services. Additionally, there is a wide contribution of chemical products into all branches of the economy; for example in Germany chemicals are the most important supplier of innovative materials for the industry. Chemicals represent 10% of the supply of input and intermediary products and they show an above average R&D content.1.12 Top 30 chemical companies in the worldIn 2007, twelve of the 30 world chemicals majors had their headquarters in the EU - representing 10% of world chemical sales. These 30 companies had a combined sales turnover of €577 billion. This is a significant increase compared to the previous year and reflects not only the positive sales development in 2006 but also the ongoing consolidation in the chemicals sector.Sources: ICIS Chemical Business and Cefic Chemdata International1.13 The EU chemical industry: number of enterprises, sales and employment by size-classThe EU chemical industry comprises 29 000 enterprises (data covering firms with no employees are excluded), 96% of which have less than 250 employees and may be considered as small and medium sized enterprises. These account for 28% of sales and 35% of employment. Only 4% of the EU enterprises employ more than 249 employees and generate 72% of total chemicals sales.1.14 Public image of the European chemical industryIn a pan European poll on the image of the EU chemical industry, chemicals in 2008 are in 6th position out of 8 benchmark industries and rank below the average. Apart from Nuclear Energy which registered a slight improvement, most sectors experienced no significant changes or followed in some cases a negative trend such as Food, Electricity and Petrol/Oil. The image of the chemical industry in 2008 is still at the same level as in 2006. This result is also in line with the average of all industries where no improvement has been perceived during the last two years.Chapter 2 International Trade2.1 External trade of EU chemicalsThe EU has always been an important player in the global chemicals market and so far it has been in a position to benefit from trade opportunities. The EU has a very substantial trade surplus in chemicals (€35.4 billion in 2007). It has a surplus with each main trading region and has broadly retained its market share in global chemicals sales over the last decade.However, the trade surplus of 2007 was the lowest one generated since 2001. Furthermore, the Trade Competitiveness Indicator (TCI), an indicator that compares the trade balance to the total trade (exports plus imports) of a region, reveals a deteriorating competitiveness of the EU chemicals industry since 2003: the TCI declined from 25% to 17% in 5 years. This shows that imports are growing faster than exports.2.2 External EU chemicals trade with major geographic blocsThe three major geographic blocs trading with the European Union in 2007 were North America, Rest of Europe and Asia (excluding Japan). Rest of Europe plays a major role thanks to Turkey and Russia. A look at the EU’s trade balance in relation to a number of key countries and regions shows that the EU position is deteriorating with certain key countries in Asia. Japan, China and India are the three only Asian countries with which the EU currently has a trade deficit for chemicals. In 2007, the EU chemicals trade balance with Asia (including Japan) was negative for the first time since nearly 20 years (Chart 2.2).2.3 External EU chemicals trade with major geographic blocs (cont’d)The external EU chemical trade surplus in 2007 was mainly attributable to North and South America (36%), other European countries (not belonging to the EU) (29.7%), Africa (13.8%).The EU chemical industry has a positive trade balance with all regions, although for Asia (excluding Japan) it should be added that the trade surplus is very small and is diminishing over time (Chart 2.3).2.4 Sectoral breakdown of EU chemicals trade surplusIn 2007, the trade surplus amounted to €35.4 billion. Specialty chemicals accounted for 41% of the EU chemicals trade surplus (excluding pharmaceuticals), with a trade surplus of €14.7, billion. With €13.6 billion consumer chemicals are the second strongest sector on the world markets, followed by polymers (€5.8 billion) and petrochemicals (€4.3 billion). Basic inorganics is the only sector with a trade deficit of €3 billion. Pharmaceuticals would account for a trade surplus of €38.3 billion which would have to be added to the €35.4 billion.2.5 EU trade balance in chemicals and other manufacturesIn 2007, the overall extra-EU chemical trade surplus decreased compared to the previous year, which is against the trend of the extra-EU trade surplus in manufacturing. The chemical sector is performing less than the manufacturing sector and accounts now for 26% of the total manufacturing trade surplus, a decrease of 5 percentage points in comparison to last year.2.6 Chemicals trade balance comparisonTo put the EU chemicals trade (including pharmaceuticals) into an international context, in comparison with the USA and Asia (including Japan), the EU is the only region with a trade surplus in chemicals and it is also the extent of the trade surplus that marks the difference. The USA has had a negative trade balance in chemicals since 2002 and the Asian trade deficit in chemicals (including Japan) has been continuously reducing since 2004 (Chart 2.6).2.7 Chemicals trade balance comparison (cont’d)In 2007, the share of EU chemicals sales exported outside the region was 26%, compared with 21% for the USA and 28% for Japan. Only 18% of the EU chemicals consumption was imported from non-EU regions. US imports accounted for almost one quarter of its consumption (22%) whereas Japan imports accounted for 20% of its consumption. (Chart 2.7)Chapter 3 Growth of the Chemical Industry3.1 Growth of production, trade and apparent consumptionOver the years 2002-2007, chemicals sales grew slightly slower than consumption (4.5% versus 5.2%). The average growth rate of imports over the last five years (7.0%) exceeded considerably that of exports (3.6%).3.2 Chemicals growth performance against total industryIn addition to providing for customers' present needs, the chemical industry is constantly developing new and improved products and processes, creating and serving completely new markets. This enables other industries to be more efficient and productive by using more effective substitute materials and products. Chemicals serve as input into basically all sectors of the economy and consequently depend on their economic performance.In the period 1997-2007, the chemical industry had an average growth rate of 1.3% whereas total industry and GDP grew by 2.2% and 2.5% respectively on average per year. These averages mask however quite different yearly growth rates in chemicals, from -2.5% in 2001 to 6.7% in 1997. The range for yearly industrial growth is much smaller, from -0.1% in 2002 to 4.8% in 2000. For 2008, the Cefic Economic Outlook Task Force expects a negative growth of 0.6% for chemicals.3.3 Sectoral production growth of EU chemicalsAll chemical sub sectors showed positive growth in 2007. Consumer chemicals were the growth leader with 5.5%, followed by petrochemicals (3.9%) and basic inorganics (1.8%). Polymers and specialty chemicals registered a very modest growth. This led to a growth rate of 2.6% for chemicals in 2007. For 2008, the outlook for most sub sectors shows a downward trend in comparison to 2007,3.4 International comparison of production growth of the chemical industryOver the past five years (2002-2007), the EU chemical industry showed the lowest growth rate compared to the biggest world regions and it is, with 1.7%, well below the world average growth of chemicals of 4.6%. Latin America and the Asia Pacific region are booming, with average growth rates in chemicals of 4.9% and 8.1% respectively over the last five years. The latter region is heavily influenced by the extraordinary performance of the Chinese chemicals sector and a booming economy and industrial sector. The relationship between chemicals growth and industry growth is in most cases the same among the regions over the last five years (industry grew faster than the chemicals sector)3.5 International comparison of production growth of the chemical industry (cont’d)The long- term trend shows that also over the years (1997-2007), the European chemical industry showed the lowest growth, whereas Asia Pacific and Latin America started their steep rise at the end of the 90’s and the growth shows no signs of stopping yet.3.6 International comparison of sales growth of the chemical industryOn a worldwide level, chemicals sales grew yearly by 4.8% over the years (1997-2007). The EU with an average sales growth rate of 3.9% is below world growth. Japan shows a meagre sales growth rate of 0.1%. The high growth countries and regions are China, Mexico, India, Taiwan, Korea and Brazil with sales growth rates between 16.5% (China) and 6.8% (Brazil)Chapter 4 Cost and prices4.1. Cost structureIn 2005, purchases by the EU chemical industry accounted for 76% of the sales value. The remaining 24% constitutes the gross value added of the sector, which comprises gross operating surplus and payroll. Among purchases, it is possible to single out the costs of trading and energy. Trading represents the cost of chemicals purchased from third parties and resold in their original condition, and amounts to 11% of the sales value. Energy costs from the purchase of feedstock and fuel and power currently account for 8% of the sales value. However, it needs to be underlined that this is an average. Certain sub sectors are much more sensitive to energy cost as for them it represents a more important input factor, for example the Chlor Alkali industry. In 2005, the payroll accounted for some 14% of the chemicals sales value. The gross operating surplus is defined as profits before taxes, financial charges and depreciation and amounts to 10%.4.2 Producer prices and overall pricesConsumer prices have on average risen more than chemical prices (including pharmaceuticals) over the years (1997-2007), 2.8% the former and 1.5% the latter. One can conclude that EU chemical industry is not boosting prices and inflation in the EU.4.3 Labour cost per employee and productivityThe payroll accounts for a significant share of chemicals production costs (14%) and is therefore a major factor in competitiveness. Labour cost per employee in the EU chemical industry (including pharmaceuticals) has increased by an average 3.5% per annum over the years (1997-2007). People in the chemical industry are highly qualified and the chemical industry redistributes part of its profit to its employees through competitive salaries. As a consequence, labour cost per employee has been increasing more than the industry average over the same period.4.4 Labour cost per employee and productivityProductivity of EU chemicals (including pharmaceuticals) is still increasing at a considerable pace - 4.1% on an average over the years (1997-2007) - and is therefore rising faster than the labour cost per employee.Chapter 5 Energy5.1 Energy use by sourceThe chemical industry upgrades energy and raw materials into products required by other industrial sectors as well as by final consumers. The cost of these inputs is a prime factor in competitiveness on world markets.From the energy sector, it consumes coal, oil products, natural gas, electricity and renewable, using them both as raw materials (feedstock) and as power and fuel. In 2006, the European chemical industry (including pharmaceuticals) used a total of 137 million tonnes of oil equivalent (TOE) of energy. Feedstock accounted for almost 60% of total energy products and fuel and power for a little bit more than 40%, taking all sources of energy into account. This implies that most of the energy used by the chemical industry as feedstock is stored in the products and through recycling can still be reused.Regarding other raw materials the chemical industry also uses a broad variety of natural or processed starting materials, e.g. metals, minerals and agricultural raw materials (sugar, starch, fats, etc.).5.2 Efficiency in energy consumptionFor many years, the EU chemical industry (including pharmaceuticals) has made strenuous efforts to improve energy efficiency, reducing its fuel and power energy consumption per unit of production. In 2006, energy consumption per unit of production in the chemical industry (including pharmaceuticals)-energy intensity-was 53% lower than in 1990. Energy efficiency is subject to decreasing returns: the higher the level of energy efficiency attained, the more difficult it becomes to make further improvements.However, over the last 16 years the chemical industry has succeeded in increasing continuously its output and at the same time keeping its energy input constant, and consequently lowered its energy intensity significantly by 4.6% per year on average.Chapter 6 Employment6.1 Employment and productionIn the EU, some 29,000 chemical and pharmaceutical companies employ a total staff of about 1.84 million, or 6% of the overall workforce in the manufacturing industry. Chemicals alone account for 1.26 million employees. Employment in the EU chemical industry has decreased by 2% over the last 10 years. Employment in the USA has experienced a steeper decline for chemicals over the same period with a decrease of 2.8%.6.2 Labour productivityThe EU chemical industry is a leading industry with high skills and productivity, due to high investment per employee and highly educated and trained employees. As a consequence, labour productivity in the EU chemical industry rose by 3.3% p.a. over the period 1997-2007.6.3 Investment per employee and personnel costsInvestment per employee and personnel cost are two important factors for the international competitiveness of the European chemical industry. The equipment of workplaces in the chemical industry is top quality and investment per employee is rather high, double the manufacturing average. Chemicals are the first manufacturing sector in terms of investment per employee.6.4 Investment per employee and personnel costs (cont’d)Additionally, the labour force employed in the chemical industry is more qualified, trained and better paid than the average industrial worker. Personnel costs for the EU chemical industry are almost 50% higher than the average of other manufacturing sectors. After pharmaceuticals, tobacco products, and automotive, the chemical industry has the fourth highest labour cost per employee of all manufacturing sectors.6.5 Labour productivity: Chemical industry versus total industryDue to strengthening global competition, the EU chemical industry has taken vigorous restructuring and cost-saving steps in order to improve competitiveness over the last decade. As a consequence labour productivity in the chemical industry is growing faster than labour productivity in total industry: 3.3% and 2.5% average annual growth 1997-2007 respectively.6.6 Level of education of workers in the chemical industryEmployees with medium and high education account for around 80% of workers in the chemical industry. While the percentage of people with lower and medium education has been decreasing since 2001, workers with a high level of education are gaining importance, accounting for almost 27% in 2005. The success of the European chemical industry depends on its well trained employees. Skills and education are an important factor in international competitiveness and the European chemical industry is facing a global challenge for talent.Chapter 7 Investment and R&D7.1 Chemical industry capital spending in the EUInvestments in innovation (including research & development R&D) are key elements in securing the future of the chemical industry. They not only promote the adaptation to and the development of new technologies and innovation, but are necessary prerequisites for the continuous adjustment of corporate structures to the needs of the market-place. It is important to notice, that the currently available figures on R&D investments give only some part of the picture as R&D is only the starting point in the path to successful innovation. Innovations spending in the companies are more and more included under business development. After some up and down movements in previous years, the ratio of investment in R&D to sales of the chemical industry (including pharmaceuticals) in the EU has been declining almost steadily since 1999. In absolute figures investment had been growing steadily between 1994 and 1999 and then declined almost continuously till 2004, with a slight recovery in the next three years.7.2 International comparison of capital spending in the chemical industryComparing the ratio of capital spending to sales of the chemical industry (including pharmaceuticals) in Europe, NAFTA and the Asia Pacific region, Asia Pacific clearly attracts most investment in R&D. NAFTA has a slightly higher investment to sales ratio than the EU over all the years (1997-2007). The heavy investment in new capacities in the Asia Pacific region is reflected in the high investment to sales ratio. Between 1997 and 2007 it was around twice the ratio of the EU, but the gap between the regions has been increasing in recent years.7.3 International comparison of research and development spendingThe high value added products of the chemical industry continuously open up new fields of application and pave the way to progress and innovation in other industries. Typical examples are the health, food, consumer goods, aerospace industry, the car industry, telecommunications, electrical engineering and electronics. Wide variations in R&D efforts are observed across the chemical industry. Turning R&D into innovation is increasingly getting importance in relation to the competitiveness of the region.Analysing the ratio of R&D spending to sales of the chemical industry it can be observed that the USA had a slightly higher ratio than the EU, but has decreased to similar levels in recent years whereas Japan has a ratio around twice as high as the other two trading regions. Japan was also the only country to barely show a decline in the ratio between 1995 and 2003.7.4 Research and development spending in EU manufacturingChemicals account for 8% of total EU manufacturing spending in R&D of €98.5 billion. They represent the 5th largest spending sector. If the R&D spending of the pharmaceutical sector is included, chemicals are the top investor in R&D in European manufacturing, accounting for almost one fourth of total R&D investment of manufacturing.Chapter 8 Sustainable Development8.1 Energy usage and greenhouse gas emissionsThe chemical industry works to develop cleaner and safer technologies, waste-recycling processes and new products to safeguard the environment (biotechnology processes, catalysts, membranes, desulphurisation plants, etc.). One aspect is increased energy efficiency. In addition to increasing the energy efficiency of its own processes, the chemical industry also helps to increase the energy efficiency of downstream users and their products through innovative inputs Between 1990 and 2006, production in the EU chemical industry (including pharmaceuticals) rose by 67%, while total energy consumption was rather stable and greenhouse gas (GHG) emissions fell by almost 32%.8.2 Energy usage and greenhouse gas emissions (cont’d)Hence, GHG emissions per unit of energy consumption have been reduced by more than 31% and GHG emissions per unit of production have been reduced by nearly 60% since 1990. This shows the enormous effort that the chemical industry is making to minimise the environmental impact of its production.8.3 Greenhouse gas emission intensity: EU versus US chemical industryIn comparison to the US, the EU has reduced its GHG emission intensity (emissions per unit of production) much more and is today more GHG emission- efficient. The US chemical industry has decreased its emission intensity by 36% since 1990, the EU by 60%.。

Synthesis of Ru/(CuIn)x Zn2(1-x)S2 Photocatalysts for Photocatalytic Hydrogen Evolution via Water-Splitting ReactionIen-Whei Chen*, Chih-Hao Tan, Chi-Tang LiDepartment of Chemical Engineering, Tatung University,Taipei 104, Taiwan, Republic of China.Tel: +886-225925252-2561-128, e-mail: iwchen@.twIntroductionMany of the photocatalysts have been synthesized for the conversion of solar energy into hydrogen energy. However, many of photocatalysts which common used for water-splitting reaction only responded under UV light irradiation such as TiO2, NaTaO3, SrTiO3, and etc [1]. Recently the interest in developing of visible-light induced photocatalysts for hydrogen evolution via water-splitting reaction has increased. The ternary semiconductors of the I-III-VI2 group (I: Cu,Ag; III : Al, Ga, In; VI:S, Se, Te) with a chalcopyrite structure have attracted attention as new functional materials such as CuInS2, CuInSe2, and CuInSe2including monovalent copper ions have intensively been investigated [2]. The chalcopyrite structure is composed of tetrahedral units in which four anions coordinate to a cation. The unit cell of the chalcopyrite type can approximately be regarded as two unit cells of a zinc-blende type piled along the c axis [3]. Therefore, the solid solution of semi-conducting system (CuIn)x Zn2(1-X)S2 can be formed by alloying the binary semiconductor ZnS into the ternary semiconductor CuInS2where ZnS is just happen to be a II-VI binary semiconductor crystallizing in zinc-blende structure at room temperature. Both end members of CuInS2- ZnS are semiconductors with a direct band gap. By varying the large value of the binary wide band gap semiconductor with the ternary narrow band gap semiconductor to suitable value, CuInS2-ZnS solid solution is capable of proceeding water-splitting reaction under visible light irradiation via hybridizing the valance band and conduction band, respectively. Particularly, it has been reported that the upper parts of valence bands of the CuInS2 are composed of a d-state of Cu mixed with a p-state of S. It has also been reported that the valence band level of CuInS2 was more negative than those of ZnS [4]. A Cu 3d orbital contributes to the valence band formation and therefore, the monovalent copper cation is attractive as the component contributing to a visible light response of solid solutions [5].For the synthesis of (CuIn)x Zn2(1-x)S2 photocatalysts, flux methods [6] have shown the ability for energy conservation by accelerating the relatively slow diffusion of reactants during reaction and the superiority of crystal controlling. On the other hand, loading of Ru as co-catalyst on prepared photocatalysts has been proposed for promotion of hydrogen evolution during the water-splitting reaction [7].In this study, (CuIn)x Zn2(1-X)S2 photocatalysts for water-splitting reaction were prepared via flux method with various ratios of CuInS2/ZnS and various reaction temperature. The prepared photocatalysts (CuIn)x Zn2(1-x)S2were then loaded with Ru to obtain the photocatalysts Ru/(CuIn)x Zn2(1-x)S2. The investigation of the characteristics and photocatalytic activity for water-splitting reaction of Ru/(CuIn)x Zn2(1-x)S2photocatalysts would finally proceeded.ExperimentalPreparation of Ru(0.5wt)/(CuIn)x Zn2(1-x)S2.Photocatalysts.The (CuIn)x Zn2(1-X)S2 photocatalysts were prepared via flux method by adding Na2S x into precursors as the flux with the various proportions of Cu2S, In2S3and ZnS precursors and different reaction temperatures. During the synthesis process, the photocatalysts were calcined at desired temperature (350-700℃) for 1 hour with heating rate of 1℃/min. All the prepared photocatalysts were followed by loading of 0.5%Ru co-catalyst via incipient wetness impregnation method. The dry residues of (CuIn)x Zn2(1-X)S2 powder were calcined in the oven at 350℃ for1 hour after immersing in an aqueous solution of 0.5wt RuCl3‧6H2O. Finally the Ru(0.5wt)/(CuIn)x Zn2(1-x)S2 was obtained.Photocatalysts Characterization.The crystal structure of prepared photocatalysts was decided by an X-ray diffraction (SHMADZU, LabX XRD 6000) operated at 40 kv and 30 mA using CuK radiation (λ=1.54178Å). The scanned range of 2θwas 20-80°. The UV-Vis diffuse reflectance spectrum was measured at room temperature with a UV-Vis spectrometer (JASCO, V-530) equipped with an integration sphere and was converted to absorbance spectrum by the Kubelka-Munk method. The band gaps (Eg) of prepared photocatalysts can be estimated by absorption band edges from UV-Vis spectrum via the formula Eg (eV)= 1240/Absorption band edge (nm), where the absorption band edge is extrapolated from the linear rise in the absorption curve. The microstructures and approximate size of prepared photocatalysts were observed by scanning electro microscope (JOEL, JSM-5600LV) with accelerating voltage of 25kv equipped with energy dispersive spectrometer (EDS), was employed for composition analysis.Photoreactivity of Water-Spltting Reaction.Photocatalytic hydrogen evolution of water-splitting reaction was conducted over the Ru(0.5wt)/(CuIn)x Zn2(1-x)S2 using Na2S(0.25M)/K2SO3(0.35M) as the sacrificial reagent. The water-splitting reactions were carried out in a gas-closed circulation system of 800 ml volume with inner irradiation. The light source was a 450 W high-pressure mercury lamp. The photocatalysts powder (1g) was dispersed in a reactant solution by a magnetic stirrer in an inner irradiation cell made of quartz. The amounts of H2 evolved were determined using gas chromatography (China chromatography 9800; MS-5A column, TCD, Ar carrier) and by volumetric measurement.Results and discussionThe structures of prepared photocatalysts were investigated by X-ray diffraction patterns. It could be seen from Fig. 1 that the photocatalysts prepared at 600℃ calcination possess the best solid solution structure of CuInS2-ZnS due to its diffraction peaks vary from both the peaks of chalcopyrite structure of CuInS2 and zinc-blende structure of ZnS, respectively. The effect of different CuInS2/ZnS ratio to the crystal structure was shown in Fig. 2 that the diffraction peaks of (CuIn)x Zn2(1-x)S2 shifted from 2Θ= 27.0, 28.6, 30.5, 33.1, and 47.5 to 2Θ= 26.9, 28.5, 30.4, 32.5, and 47.4 with X=0.01 to X=0.14. It could be seen from Fig. 2 that the chalcopyrite structure increased with the increasing of CuInS2/ZnS ratio.Fig. 1. X-ray diffraction patterns of (CuIn)0.09 Zn 1.82S 2 synthesized via flux method withvarious temperature (a)350℃, (b)400℃, (c)500℃, (d)600℃, (e)700℃.Fig. 2. X-ray diffraction patterns of (CuIn)x Zn 2(1-x)S 2 synthesized with various molar ratio (a)x=0, (b) x=0.01, (c) x=0.03, (d) x=0.05, (e) x=0.09, (f) x=0.14, (g) x=0.22 , (h) x=0.5 , (i) x=1.The UV-Vis diffuse reflectance spectra of (CuIn)0.09 Zn 1.82S 2 synthesized with various temperature were shown in Fig.3. The absorption of photocatalysts prepared under 600℃ calcination possessed the highest absorption shoulder and longest absorption band edge due to its better crystal structure of solid solution. The effect of different CuInS 2/ZnS ratio to the absorption of UV-Vis diffuse reflectance spectra was shown in Fig. 4 that the absorption band edges shifted to higher wavelength with the increasing of CuInS 2/ZnS ratio. The red shift represented that the photocatalysts had better activity of visible light response. However, CuInS 2 (X=1) seemed to have the highest absorption value of UV-Vis diffuse reflectance spectrum, it had no activity for water-splitting reaction because of its lack of suitable band gap.The surface structure and particle size could be seen from SEM images of prepared photocatalysts shown in Fig. 5 and Fig. 6. It could be seen from Fig. 5 and Fig. 6 that the particle size of prepared photocatalysts increased both when the calcination temperature was elevated and the ratio of CuInS 2/ZnS wass increased, respectively.The specific elements could be identified from EDS spectra for (CuIn)x Zn 2(1-x)S 2 synthesized with various molar ratio.

The reactor was designed for water-splitting reaction in Na2S(0.25M)/K2SO3(0.35M) sacrificial reagent solution with inner irradiation. H2evolution from aqueous sacrificial reagent solution were shown for (CuIn)x Zn2(1-x)S2. It could be seen from Fig.8 that the photocatalysts prepared at 600℃possessed the highest H2evolution rate. Fig. 9 showed that the optimum (CuIn)x Zn2(1-x)S2 photocatalysts was obtained at X=0.14 in order to reach the highest H2 evolution rate.Fig. 8.

Hydrogen evolution rate over (CuIn)x Zn2(1-x)S2 synthesized with various molar ratio of CuInS2/ZnS.ConclusionsFlux method can be used for preparation of photocatalysts to high purity and homogeneity in shortened reaction time. Especially the adding of Na2S x as flux not only helps to lower the reaction temperature but also to create an atmosphere without oxygen and H2O. Form the results XRD patterns, it was shown that the prepared photocatalysts possess the best crystal structure as CuInS2/ZnS solid solution under 600℃calcination. It also can be found from XRD patterns of (CuIn)x Zn2(1-x)S2 that the chalcopyrite structure is getting more obvious with increasing molar ratio of CuInS2/ZnS. Form UV-Vis diffuse reflectance spectra of Ru(0.5wt)/(CuIn)0.09 Zn1.82S2, it can be seen that the photocatalysts synthesized at 600℃ has the highest absorption shoulder. It also can be seen from UV-Vis diffuse reflectance spectra of Ru(0.5wt)/(CuIn)x Zn2(1-x)S2 that the absorption band edge shifts to longer wavelength when the ratio of CuInS2/ZnS increased. The SEM images of prepared photocatalysts show that the particle size of prepared photocatalysts increased with the elevation of calcination temperature and increasing of CuInS2/ZnS ratio, respectively. EDS results confirmed that the prepared photocatalysts contained target elements of Cu, In, Zn, and S. From the results of hydrogen evolution rate via water-splitting reaction, it is obvious that the adding of Na2S(0.25M)/K2SO3(0.35M) sacrificial reagent promotes the hydrogen evolution rate in water-splitting reaction. Finally, the highest hydrogen evolution rate of 967.9µmole/h was obtained for the water-splitting reaction using Ru(0.5wt%)/(CuIn)0.14Zn1.72S2photocatalyst prepared at 600℃and adding of Na2S(0.25M)/K2SO3(0.35M) sacrificial reagent.
