| 1 | A 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 | 2019 | Nano Research2019，12，11： | 12 |

| 5 | Low Li ion diffusion barrier on low-crystalline FeOOH nanosheets and high performance of energy storage显示文摘To obtain symmetric supercapacitors(SCs)with high energy density,it is critical to fabricate an electrode with wide potential window and excellent capacitive performance.Herein,by using the strong double hydrolysis reaction between anions and cations,the FeOOH nanosheets on the surface of activated carbon cloth(FeOOH@AC)are prepared through a simple hydrothermal process.The FeOOH@AC electrode exhibits maximum capacitance of 4,090 mF·cm^−2 at wider potential window-1–0 V and 3,250 mF·cm^−2 at 0–1 V versus SCE in 2 M LiNO3 electrolyte.With two pieces of FeOOH@AC electrodes the obtained symmetric SC can operate at the voltage window of 2 V.This FeOOH symmetric SC shows high energy density of 13.261 mWh·cm^−3 at a power density of 14.824 mW·cm^−3 and maintains 4.175 mWh·cm^−3 at a maximum power density of 118.564 mW·cm^−3,as well as excellent charge storage capacity and cyclic stability.Li ion adsorption and diffusion mechanism on the(200)facets of FeOOH are explained by the density functional theory(DFT)calculations.The simple synthesis process and excellent capacitance performance of the FeOOH@AC composite make it a very promising candidate for high performance symmetric SC electrodes. | Jien Li Shuang Luo Congcong Wang Qian Tang Yanwei Wang Xiangyu Han Hao Ran Jing Wan Xiao Gu Xue Wang Chenguo Hu | 2020 | Nano Research2020，13，3： | 1 |
