摘要：

氢气具有质量轻、热值高、燃烧产物清洁等优点,被认为是理想的能源载体。氢气既能作为燃料电池的燃料,又能作为储能介质调节风能、太阳能发电系统的随机性、间歇性,正在成为未来能源的重要组成部分。为了促进电解水制氢技术与装备发展,研究高效电催化剂十分重要。本文围绕"粉末型"与"自支撑型"电催化剂结构特征,讨论基于二硫化钼（MoS2）的析氢电催化剂的研究现状,阐述了催化活性位点调控策略与提高导电性两条技术途径,并以析氢过电位和塔菲尔曲线斜率为依据,比较不同方法制备的二硫化钼电催化剂的催化活性。表明提高二硫化钼晶相稳定性、调节其电子结构和优化催化电极结构等方法,将进一步提高基于二硫化钼的析氢催化电极性能。
