摘要
Abstract
H2 as a kind of clean energy is considered to be one of the most promising alternative energy sources to alleviate energy crisis and reduce environmental pollution.Using renewable energy to electrolyze water for H2 production is an important method for green hydrogen production.However,low current density and high energy consumption are the problems of industrial electrolysis of water for hydrogen production.Increasing the current density is the most direct way to increase the hydrogen production rate,but if the electrocatalyst is not optimized,increasing the current density will cause the increase of power consumption.Therefore,it is urgently needed to develop high-performance electrocatalysts for the hydrogen evolution reaction(hereinafter referred to as"HER")with low overpotential under high current density.Firstly,the mechanism of HER reaction in acidic and alkaline media was introduced,including Volmer-Heyrovsky and Volmer-Tafel,and the requirements of high performance electrocatalysts under high current density were put forward.Then,the research progress of precious metal and non-precious metal HER electrocatalysts in recent years from the aspects of single atom electrocatalysts,alloy electrocatalysts and heterostructure electrocatalysts were reviewed.Finally,the challenges and opportunities in the future for the development of HER electrocatalysts were discussed.关键词
