1A review on synthesis of graphene,h-BN and MoS2 for energy storage applications:Recent progress and perspectives显示文摘The significance of graphene and its two-dimensional(2D)analogous inorganic layered materials especially as hexagonal boron nitride(h-BN)and molybdenum disulphide(MoS2)for“clean energy”applications became apparent over the last few years due to their extraordinary properties.In this review article we study the current progress and selected challenges in the syntheses of graphene,h-BN and MoS2 including energy storage applications as supercapacitors and batteries.Various substrates/catalysts(metals/insulator/semiconducting)have been used to obtain graphene,h-BN and MoS2 using different kinds of precursors.The most widespread methods for synthesis of graphene,h-BN and MoS2 layers are chemical vapor deposition(CVD),plasma-enhanced CVD,hydro/solvothermal methods,liquid phase exfoliation,physical methods etc.Current research has shown that graphene,h-BN and MoS2 layered materials modified with metal oxide can have an insightful influence on the performance of energy storage devices as supercapacitors and batteries.This review article also contains the discussion on the opportunities and perspectives of these materials(graphene,h-BN and MoS2)in the energy storage fields.We expect that this witen review article including recent research on energy storage will help in generating new insights for further development and practical applications of graphene,h-BN and MoS2 layers based materials.Rajesh Kumar Sumanta Sahoo Ednan Joanni Rajesh Kumar Singh Ram Manohar Yadav Rajiv Kumar Verma Dinesh Pratap Singh Wai Kian Tan Angel Perez del Pino Stanislav A.Moshkalev Atsunori Matsuda 2019Nano Research2019,12,11:12
2金属相二硫化钼在能量储存与转化中的应用进展显示文摘金属相二硫化钼具有较大的层间距、较高的导电率以及丰富的活性位点,在能量储存与转化领域显示出广阔的应用前景。本文综述金属相二硫化钼在能量储存与转化中的研究进展。首先介绍金属相二硫化钼的晶体结构与电子结构,概述金属相二硫化钼的制备方法,即自上而下(锂插层剥离法)和自下而上(溶剂/水热法)等。然后总结金属相二硫化钼及其复合材料在能量储存与转化领域如氢析出反应、锂(钠)离子电池和超级电容器中的应用进展。最后指出目前金属相二硫化钼还存在合成工艺不可控和结构稳定性差等问题,而对其结构和性质之间的深入研究有望从根本上改善金属相二硫化钼的性能及其在能量储存与转化领域中的实际应用价值。徐晨曦 胡安俊 舒朝著 龙剑平 2020材料工程2020,48,9:5
3Porous-hollow nanorods constructed from alternate intercalation of carbon and MoS2 monolayers for lithium and sodium storage显示文摘Weak ion diffusion and electron transport due to limited interlayer spacing and poor electrical conductivity have been identified as critical roadbacks for fast and abundant energy storage of both MoS2-based lithium ion batteries (LIBs) and sodium ion batteries (SIBs). In this work, MoS2 porous-hollow nanorods (MoS2/m-C800) have been designed and synthesized via an annealing-followed chemistry-intercalated strategy to solve the two issues. They are uniformly assembled from ultrathin MoS2 nanosheets, deviated to the rod-axis direction, with expanded interlayer spacing due to alternate intercalation of N-doped carbon monolayers between the adjacent MoS2 monolayers. Electrochemical studies of the MoS2/m-C800 sample, as an anode of LIBs, demonstrate that the superstructure can deliver a reversible discharge capacity of 1,170 mAh·g^-1 after 100 cycles at 0.2 A·g^-1 and maintain a reversible capacity of 951 mAh·g^-1 at 1.25 A·g^-1 after 350 cycles. While for SIBs, the superstructure also delivers a reversible discharge capacity of 350 mAh·g^-1 at 0.5 A-g-1 after 500 cycles and exhibits superior rate capacity of 238 mAh·g^-1 at 15 A·g^-1 .The excellent electrochemical performance is closely related with the hierarchical superstructures, including expanded interlayer spacing, alternate intercalation of carbon monolayers and mesoporous feature, which effectively reduce ion diffusion barrier, shorten ion diffusion paths and improve electrical conductivity.Laiying Jing Gang Lian Junru Wang Mingwen Zhao Xizheng Liu Qilong Wang Deliang Cui Ching-Ping Wong 2019Nano Research2019,12,8:3
4PANI/MoS_2复合材料的制备及其电化学性能研究显示文摘采用原位聚合法制备不同摩尔比的PANI/MoS_2纳米复合材料。通过X射线衍射、红外光谱、透射电镜等手段,对所制备的材料进行了结构和微观形貌的表征,结果表明:所制备的聚苯胺呈现棒状纳米纤维包覆在卷曲的纳米鳞片MoS_2片层上形成了PANI/MoS_2纳米复合材料。通过循环伏安法、恒流充放电等测试手段对材料的电化学性能进行了研究,结果表明:在不同电流密度下PANI∶MoS_2=1∶0.1的二元复合物比电容明显高于纯聚苯胺,在1 A/g时PANI∶MoS_2=1∶0.1的二元复合物的比电容值可达942.5 F/g,相比于同电流密度下的PANI的400.5 F/g的高出一倍。表明适量的MoS_2的掺入有助于提高PANI电极材料的电化学电容特性。阿比旦.阿布都乃则尔 张艳慧 阿孜古丽.木尔赛力木 王琳 兰海蝶 2018当代化工2018,47,5:1
