非贵金属析氢电催化剂的结构调控研究进展

Recent Advancements in the Regulation of Structure of Non-Noble Metal Electrocatalysts for the Hydrogen Evolution Reaction

能源危机和环境污染日益严重,寻找可持续且清洁的新能源成为趋势,而氢能被视为最理想的选择。贵金属基催化剂虽活性优异但成本高、稳定性差,因此开发可代替如铱(Ir)和钌(Ru)等贵金属催化剂的非贵金属催化剂是研究热点,而掌握析氢反应(Hydrogen evolution reaction,HER)机理是合成新型高效电催化剂的关键。本文综述了近年来非贵金属基HER催化剂的研究进展,围绕Fe、Co、Ni和Mn等非贵金属析氢电催化剂构建和提高催化活性的策略进行了讨论,其中包括组分调控和缺陷工程等方面。此外,还展望了HER催化剂的应用前景。

With the increasingly serious energy crisis and environmental pollution,it is a trend to find sustainable and clean new energy,and hydrogen energy is regarded as the most ideal choice.Although noble metal-based catalysts have excellent activity,they also have the disadvantages of high cost and poor stability.Consequently,the development of non-noble metal catalysts which can replace the precious metal catalysts such as iridium(Ir)and ruthenium(Ru)has become the current research hotspot,and understanding the mechanism of hydrogen evolution reaction(HER)is the key to synthesize new efficient electrocatalysts.The recent non-noble metal based HER catalysts are reviewed in this paper.The strategies for constructing and improving the catalytic activity of non-noble metals such as Fe,Co,Ni and Mn,including the regulation of component and the defect engineering are discussed.In addition,the past development and the challenges faced by HER catalyst in the future are also outlined.The application prospect of HER catalyst is also predicted.
