Research Progress of Alkaline Electrocatalytic Hydrogen Evolution Catalysts

电解水制氢是零碳排放氢经济的必要前提。碱性环境下的电催化析氢反应(HER)是电解水技术主要的能量转换过程之一。然而由于碱性析氢反应机理仍处于争论中,严重影响了催化剂的优化设计。本文基于当前碱性HER反应机理的认知,总结多种催化材料对碱性HER催化性能的研究进展,并展望了未来发展的方向。

The production of hydrogen by water electrolysis is an essential prerequisite of the hydrogen economy with zero carbon emission. Electrocatalytic hydrogen evolution reaction in alkaline environments is one of the main energy conversion processes in water electrolysis technology. However, the reaction mechanism of alkaline hydrogen evolution is still under debate, which seriously affects the optimal design of the catalyst. Based on the current understanding of alkaline HER reaction mechanism, this paper summarizes the research progress of various catalytic materials on the catalytic performance of alkaline HER, and looks forward to the future development direction.
