摘　　要：氢气被认为是安全并可持续供应的一种清洁能源,在缓解化石能源短缺和环境污染等方面具有十分重要的作用,而电催化分解水是产氢的有效途径之一。二硫化钼(MoS2)因具有较低的氢吸附吉布斯自由能(ΔG_(H))而被广泛用于电催化析氢过程。综述了提升MoS2电催化析氢性能的方法,通过贵金属掺杂诱导MoS2产生相转变或者暴露更多催化活性位点,以及通过过渡金属和非金属掺杂使MoS2暴露更多活性位点或者产生硫空位。同时,针对MoS2催化性能的提升提出了一些建议。Hydrogen is regarded as a safe and sustainable supply of clean energy,which plays a very important role in alleviating the shortage of fossil energy and environmental pollution.Electrocatalytic water splitting is one of the effective ways to produce hydrogen.MoS2 has been widely used in electrocatalytic hydrogen evolution reaction because of its lowΔG_(H).This article summarizes the methods for improving the electrocatalytic hydrogen evolution performance of MoS2,including inducing phase transition or exposing more catalytic active sites in MoS2 through noble metal doping,and exposing more active sites or generating sulfur vacancies in MoS2 through transition metal and non-metal doping.Meanwhile,some suggestions have been put forward to improve the catalytic performance of MoS2.
