氮掺杂石墨烯复合材料的制备及其电化学性能研究氮掺杂石墨烯（N-doped graphene）复合材料是一种具有重要应用潜力的新型材料，其制备方法和电化学性能研究一直是材料科学领域的热点研究方向之一。

本文将详细介绍氮掺杂石墨烯复合材料的制备方法及其电化学性能研究的进展。

首先，关于氮掺杂石墨烯的制备方法，目前常用的方法有热还原法、化学气相沉积法、溶胶-凝胶法和电化学法等。

其中，热还原法是较为常用的一种方法。

该方法通常是将石墨烯氧化物（GO）与含氮化合物（如尿素、三氯氰胺等）一起进行高温还原，通过热解的过程实现石墨烯的氮掺杂。

此外，化学气相沉积法是一种在高温下通过金属催化剂的作用将含氮化合物分解并封装在石墨烯层中的方法。

溶胶-凝胶法则是通过将石墨烯氧化物与含氮化合物溶解在溶液中，然后进行混合、干燥和热处理等步骤来实现氮掺杂。

最后，电化学法是通过电化学还原法将石墨烯氧化物在某种电解质溶液中还原为氮掺杂石墨烯。

利用以上方法制备的氮掺杂石墨烯复合材料具有较好的电化学性能。

例如，N-doped graphene具有较高的导电性和电化学活性，能够在电化学储能和传感器等领域发挥重要作用。

此外，氮掺杂还能够改变石墨烯的能带结构，增加其化学吸附活性，并提高其电催化性能。

此外，氮掺杂石墨烯还具有优异的光电性质，可应用于光电器件等领域。

在氮掺杂石墨烯复合材料的电化学性能研究方面，关键是研究其在储能和催化领域的应用。

例如，在储能方面，研究人员利用N-doped graphene构建超级电容器并取得了不错的电化学性能。

N-doped graphene具有较高的比表面积和良好的离子传输性能，可以增加储能电极的容量和循环寿命。

在催化方面，N-doped graphene在电催化还原CO2、氧化甲醇和氢氧化物等反应中表现出良好的活性和选择性。

研究人员还通过合成N-doped graphene/负载金属纳米材料复合体系来提高催化性能。

石墨烯基础材料的光电特性Inhwa Jung在这研究报告中，石墨烯基础材料的光电性能被调查，特别是研究具有氧化石墨单层的石墨烯氧化物的物理和化学性质和它的化学简式与石墨的不同。

尽管氧化石墨在一百多年前就被Brodie（在1859年）合成，但直到现在特殊层还没被深入研究，与我们正在研究的石墨烯氧化物比较，物理学家在原始石墨烯(石墨的一个层)发现了卓越的物理输送特性同时也显示石墨烯在纳米电子方面的潜力;这提高我们对包括石墨烯氧化物在内的化学法改变石墨性质的兴趣。

从石墨烯的光学性质方面来看，为了识别和测量石墨烯基底的有效光学性质，由于由硅上的薄介电层组成的基底的作用，一个直截了当的方法被提出。

通过这个方法和优化介电层的厚度，获得石墨烯基底独特晶片和基底的的巨大差别。

选择合适的光学性能和介电层的厚度，氧化石墨的有效折射率和光学吸收系数可以减少氧化石墨，通过对比预测与实际测量的差别可以获得石墨烯。

椭圆光度法成像是一种为光学成像和表征超薄材料（1nm~）例如特殊化学法改变的石墨烯晶片和少层氧化石墨烯晶片保持电势的方法，单独使用椭圆光度法成像无论能否确定它的光学性质和厚度都是非常有趣的，传统的光谱椭圆光度法也可以应用到比特殊晶片宽数毫米的多层叠加的氧化石墨上。

利用两种成像方法得到的结果对比最大的区别在于光学性质的差异。

观察热处理过的单体和多层叠加，多层叠加和单层的区别类似氧化石墨（无论是特殊晶片还是多层叠加）的对比结果。

分别从轮廓仪和AFM得到厚度，解释厚度和光学性质在热处理时会改变的模型被提出。

电学特征是前面提及的异常原始石墨性能基本的技术领域，通过在真空中加热单层石墨氧化物(沉积于基体)对材料的电阻率进行了监测。

通过监测随时间和温度响应的电导率能够表明,导电率的变化可能与一个激活的化学过程有关, 并由此可以获得活化能(势垒高度)。

通过高达85 S/m的时间温度曝光可以知道单层的氧化石墨的导电率，其次在真空中加热并与气相肼发生化学还原可以成倍地得到更高的导电率，如原始石墨一样，氧化石墨导电率对电场方向很敏感，伏安测量还表明，氧化石墨的电气性能与石墨烯存在差别。

石墨烯是由sp2杂化的碳原子按蜂窝状结构排列成的单层、二维片状结构。

C-base Material Applied In Lithium Ion BatteryAbstractSince its first commercialization of the Li-ion battery from Sony Laboratories, Carbon-based rechargeable batteries have gained extensive attention, wherein metallic lithium is replaced by a carbon host structure that can reversibly absorb and release lithium ions at low electrochemical potentials. Thousands of scientific groups have taken Carbon-base material as the anode for the lithium ion battery. By critically analysing latest research papers, we aim to address the benefits and issues of Carbon materials, as well as outline the most promising results and applications so far.Keywords: Anode, Carbon-base material, Lithium Ion BatteryIntroductionThere is increasing worldwide demand for advanced Li ion batteries (LIBs) with higher energy capacity and longer cycle lifetime for applications in mobile communication devices, portable electronic devices, electrical/ hybrid vehicles, and miscellaneous power devices. Traditional highly graphitized carbon anode materials show low Li storage capacity (<372 mAh/g) due to limited Li ion storage sites within sp2 carbon hexahedrons. To go beyon d the “ion” site limitation, many studies have explored Carbon-based materials for higher electrochemical energy storage.As originally reported by Dahn et al. in 1995, an anode comprising single layers of graphene can host two times as many Li+ ions as conventional graphite. The storage of one lithium ion on each side of graphene results in a Li2C6 stoichiometry that provides a specific capacity of 744 mAh/g — twice that of graphite (372 mAh/g). Differently from graphite, in which lithium is intercalated between the stacked layers, single-layer graphene can theoretically store Li+ ions through an adsorption mechanism, both on its internal surfaces and in the empty nanopores that exist between the randomly arranged single layers. In other reported studies, reduced graphene oxide (RGO) is also a very promise substance for lithium-ion storage. During the first Li+ insertion, RGO exhibited incredibly high-capacity values of >2000 mAh/g, which is higher than the theoretical capacity of single-layer graphene. However, this amazing capacity is not fully released after de-insertion due to the massive irreversibility of the first lithiation step. This phenomenon, also observed for other Li-ion anode materials, can be attributed mainly to the irreversible reduction of the electrolyte to form a surface passivation layer on the active particles, namely, the solid electrolyte interphase.Owing to high conductivity and stability, C-based material can also be used to couple with other electroactive materials such as metal (or metal oxide) nanoparticles. These kind of composites provides reversible alloying (with SnO2 or Si nanoparticles), insertion (with TiO2) or conversion (with Fe2O3 or Co3O4) reactions with lithium, thus allowing considerably higher storage capacities. The extensive and highly conductive carbon matrix established by graphene layers improves the electrical conductivity of the composite and buffers eventual volume changes taking place in electrodes based on alloying or conversion materials during cycling.In this review, we critically analyze latest research papers and demonstrate C-base material can be used in different aspect in the electrochemistry field.Graphene as an active materialIn lithium-ion batteries (LIBs), Li+ ions continuously shuttle between a lithium-releasing cathode (commonly a layered lithium metal oxide) and a lithium-accepting anode (commonly graphite). The amount of ions hosted per gram of material determines the capacity — and thus the energy — of the battery. Similar to graphite, graphene can be used as an anode for hosting Li+, both as such and as a carbonaceous matrix in composites with other materials also capable of storing lithium.Graphene-prepared by different methodsGraphene nanosheets have significant disorder/defects, large specific surface area, and remaining surface functional groups. All these factors have ever been proposed to be related to additional Li storage capacity in nongraphite carbonaceous materials with high specific capacities. Dengyu Pan et al synthesize a highly disordered graphene nanosheet with an outstanding capacity of 794-1054 mAh/g. They prepare graphene nanosheets with different disorder level by changing reduction methods and conditions. A series of graphene nanosheet samples were prepared from graphene oxide (GO) sheets via three different routes including hydrazine reduction, pyrolytic deoxidation and electron beam irradiation.Figure 1 Raman spectra of four different reductionsRaman spectra with characteristic G and D bands sensitive to defects, disorder, and carbon grain size have extensively been used to characterize carbon materials. The G band arises from the zone center E2g mode, corresponding to ordered sp2 bonded carbon, whereas the D band is ascribed to edges, other defects, and disordered carbon. The I D/I G intensity ratio is a measure of disorder degree and average size of the sp2 domains. Figure 1 displays the Raman spectra of four different reduction samples. Figure 1b shows Electron Beam reduced GO has a I D/I G of 1.51 and Hydrazine Reduced GO has a smaller I D/I G of 0.74. Figure 1c displays the Raman spectra of the pristine and pyrolytic GO. For the 300℃pyrolytic GO, however, the G band disappears. The disappearance of the G band arises from the destruction of the E2g symmetry and structural distortion of sp2 domains induced by the low-temperature pyrolysis.Figure 2 shows reversible capability verse cycle Figure 2 Cycle performance number of above materials. (i) natural graphite (ii)pristine GO (iii) hydrazine-reduced GO (iv) 300℃pyrolytic GO (v) 600 ℃pyrolytic GO (vi) andelectron-beam-reduced GO. It can be easily to drawthe conclusion that the material with higher I D/I Gdisplays a better electrochemistry performance.They can correlate the reversible capacity with theRaman intensity ratio. That is, Raman intensityratio (I D/I G) may be the key structural parameter for evaluation of the reversible capacity. What is more, they propose a mechanism to explain how Raman intensity ratio is correlated with the reversible capacity. The I D/I G ratio describes disorder degree in carbonaceous materials because the D band is ascribed to disordered carbon, edge defects, and other defects.Scheme 1 The Li storage model of graphene nanosheetsThe Li storage model of graphene nanosheets is suggested in Scheme 1. The defects at the interface between the nanosheets and the electrolyte may accommodate irreversible Li present in SEI films, whereas the defects at edge sites and internal (basal-plane) defects (vacancies etc.) of the nanodomains embedded in graphene nanosheets may involve reversible Li storage because these defects do not come into contact with the electrolyte. Some Li ions may be stored reversibly between (002) planes, but the defect-based reversible storage may predominate. The notable capacity fading observed in the highly disordered samples may be ascribed to the disorder-induced structure instability.Graphene-doped by other elementsAnother method to improve defects and vacancies is to dope other elements to graphene. It is generally believe that lithium ion batteries (LIBs) using a bulk material such as layered graphite or metal oxide as an anode are capable of achieving a high energy density by storing charges in the bulk of the material, but suffer from a low power density compared to another important electrochemical storage device, electrochemical capacitors (ECs).In order to meet the requirements for LIB applications, Zhong-Shuai Wu et al synthesize the doped graphene electrodes with extremely high rate and large capacity made by heteroatom (N, B)- doped chemically derived graphene. At a low charge/discharge rate of 50 mA /g, the doped graphene electrodes exhibit a very high capacity of 1043 mAh/g for N-doped graphene and 1549 mAh/g for B-doped graphene with greatly improved Coulombic efficiency and cycle performance in comparison with undoped graphene. More importantly, the doped graphene can be quickly charged and discharged for a very short time of 1 h to several tens of seconds, showing high rate capability and excellent long-term cyclability at the same time.At a very high current rate of 25A /g (seen in Figure 3), corresponding to a charge time of28s (126C) for the N-doped graphene and 33s (106 C) for the B-doped graphene, the reversible capacity can still reach 199 mAh/g for the N-doped graphene and 235 mAh/g for the B-doped graphene.Figure 3 The rate performance of N-doped (c) and B-doped (d) graphene What’s more, these doped graphene sheets show a higher thermal stability of 531℃for the N-doped graphene and 588℃for the B-doped graphene than that of pristine graphene (502℃) due to the simultaneous doping and reduction during the doping process. The author suppose that improved electrical conductivity, and thermal stability of the doped graphene allow rapid surface Lit absorption and ultrafast Li+ diffusion and electron transport, thus making this material superior to conventional bulk electrode materials based on Li intercalation and conversion reactions. Graphene as an inactive materialLiCoO2, LiMn2O4 and LiFePO4 (hereafter referred to as LMO) are some of the most commonly used cathode materials in LIBs. The cycle life and rate capability of these materials are generally limited by their poor electrical conductivity. Introducing low-cost conductive additives (for example, carbon black) into the composite electrodes commonly solves this issue. Nevertheless, owing to their amorphous structure, carbon blacks possess a rather low electrical conductivity, with respect to more crystalline carbons such as graphene.Thousands of papers related to graphene are applied in LIB system, we demonstrate an interesting strategy that Shubin et al Yang synthesize a sandwich-like graphene-base titaniananosheets (seen scheme 2).Scheme 2 Illustration of sandwich compositeTo circumvent the drawbacks of titania, graphene with high electrical conductivity have beenutilized as matrices or conductive additives to improve its electrochemical performance. Thegraphene in the composite serve as a mini current collector, which can improve electronconductivity and leads to an dramatic improvement of electrochemical performance. As shown inthe Figure 4, it is striking that a high first discharge capacity of 269 mAh/g is achieved at a currentrate of 0.2 C (Figure 4), corresponding to a lithium insertion coefficient of 0.8 in Li0.8TiO2 . Thisvalue is much higher than the theoretical capacity of titania (167.5 mAh/g ) with the maximumcoefficient of 0.5 (Li0.5TiO2), suggesting the existence of additional lithium storage sites in ourG-TiO2 nanosheets.Figure 4 The cyclability of sandwich composite&TiO2ConclusionCarbon-base material, which can not only be served as an anode but also be used as an inactive material, plays an important role in lithium ion battery system. It arises from graphite, but it’s better than graphite for its breaking down the theoretical limitation of capacity( 372mAh/g ).This is particularly appropriate for the field of electrochemical energy storage, in which ‘graphene fever’ has reached rather high levels due to the continuous need for new materials that can meet the market’s performance requirements. We believe that Carbon-base material, especially graphene, will dominate the market of anode for a long time.Reference[1] Dengyu Pan et.a l. Li Storage Properties of Disordered Graphene Nanosheets.
