摘要
二硫化钼(MoS_(2))已成为电化学析氢反应(HER)中铂催化剂的廉价替代品。1T-MoS_(2)是MoS_(2)的金属相,由于其具有优异的导电性和更多的电化学活性位点,因此成为了比2H-MoS_(2)更具前景的理想催化剂材料。本文综述了1T相MoS_(2)的制备及在HER中的应用。首先,比较了1T-MoS_(2)和2H-MoS_(2)几何结构及电子结构的差异,从“自上而下”及“自下而上”的角度概述了1T-MoS_(2)常用制备方法,总结1T-MoS_(2)及1T-MoS_(2)基材料在HER领域的应用;最后指出现阶段关于1T-MoS_(2)的研究中仍存在的一些关键问题。
Molybdenum disulfide(MoS_(2))has become an inexpensive alternative to platinum catalysts in electrochemical hydrogen evolution reactions(HER).1T-MoS_(2) as the metallic phase of MoS_(2) now emerge as a more promising catalyst material than 2H-MoS_(2),due to its extraordinary conductivity and more electrochemical activity sites.In this review,the preparation of 1T phase MoS_(2) and its application in HER are reviewed.Firstly,the geometries and electronic structures of 1T-MoS_(2) and 2H-MoS_(2) are discussed and compared.We introduced kinds of preparation methods of 1T-MoS_(2),from a perspective of"up-bottom"and"bottom-up"preparation pathways.Then,the application of 1T-MoS_(2) and 1T-MoS_(2) based materials in the field of HER were summarized.Finally,some key issues were proposed in the current research on 1T-MoS_(2).
