摘　　要：近年来,类石墨烯二维层状化合物以其独特的物理化学性质,成为国内外研究的热点.二维金属硒化物在很多应用领域,具有超越金属硫化物与石墨烯的独特性质,特别是在电化学方面.本文简要介绍了二维层状金属硒化物的物理结构与制备方法,特别关注了其在电化学储能,包括锂离子电池、钠离子电池、超级电容器和电催化中的应用,并展望了二维层状金属硒化物的研究前景.Clean and sustainable energy supply is regarded as the most significant problems in the 21 st century, which is ultimately related to our daily lives, global environment, economy, and human health. Although fossil fuels as the main energy sources will continue to play a crucial role in responding our energy needs in the future, they come at a tremendous price, including a rapid increase in greenhouse gas emissions and long-lasting environmental pollution. The imminent shortage of fossil fuels and growing ecological concerns is pushing scientists and engineers to exploit sustainable, clean, and highly efficient technologies to supply and store energy. With the permanently increasing demand in energy resources, massive efforts have been devoted to developing advanced energy storage and conversion systems. Novel materials hold the key to fundamental advances in energy conversion and storage, both of which are vital in order to meet the challenge of global warming and the finite nature of fossil fuels. Graphene as one of the most successful functionally nanomaterials, which have attracted great attention due to their unique properties of large surface area, superior electric and thermal conductivities, high mechanical flexibility, chemical stability, which render them great choices as alternative electrode materials for electrochemical energy storage systems. The ultrathin two-dimensional（2D） morphology of graphene with unique properties is triggering a great deal of attention toward the family of 2D structures. The types of 2D inorganic graphene analogues nanomaterials such as metal dichalcogenides have also been studied and applied in various applications including electronics, optoelectronics, energy storage devices, solar energy, electrocatalysts for hydrogen evolution reaction and so on. Layered transition metal dichalcogenides（Mo S2, Mo Se2, WS2, WSe2, etc.） as the typical graphene analogues, which are a chemically diverse class of compounds having band gaps from 0 to ～2 e V and remarkable electrochem
