摘　　要：利用催化剂电化学分解水产氢是实现氢能的有效利用,缓解当前严重的环境问题和能源危机的有效途径。但是,目前这一技术仍存在转化效率低、应用成本高等诸多局限,而设计和合成具有高活性、低成本及高稳定性的电催化剂是解决这些问题的关键。二硫化钼作为一种廉价易得的二维材料,对电催化析氢表现出良好的催化活性,因而有望取代贵金属催化剂从而实现工业化应用。但是其固有惰性基面的存在及导电性差的问题限制其析氢催化性能的进一步提升。本文从电解水的机理及二硫化钼的结构特性出发,综述二硫化钼基电催化剂的改性策略及在析氢领域的最新研究进展,重点论述不同改性策略对析氢催化反应的内在作用机理及存在的问题,并指出目前二硫化钼催化剂应朝着多种改性措施相结合、理论指导实验以及快速有效合成的方向进一步发展。Electrochemical water splitting by electrocatalyst is one of the most promising ways for generating and utilizing hydrogen energy,and it is critical to effectively mitigate the serious energy crisis and environmental pollution.However,the widely application of electrocatalysis technology is still limited by its low conversion efficiency and high cost.For this purpose,developing electrocatalyst materials with high activity,low cost and well stability are critical to solve the above limitions.As an inexpensive and readily available two-dimensional material,molybdenum disulfide is considered as a promising candidate to replace noble metal catalysts due to its good catalytic activity for electrocatalytic hydrogen evolution,which realize the industrial application.However,the inert basal plane and low electrical conductivity of pristine MoS2 limit the further improvement of its electrocatalytic performance.In this review,starting from the mechanism of water electrolysis and the inherent feature of molybdenum disulfide electrocatalysts,the latest research progress of various modification strategies to improve the catalytic performance of MoS2 was summarized.Moreover,the intrinsic mechanism of different modification strategies in the catalytic reaction process was highlighted and their respective drawbacks were indicated.Finally,it was pointed out that the current molybdenum disulfide catalyst should be further developed towards a combination of multiple modification measures,theoretical guidance for experiments,and rapid and effective synthesis.
