摘要
以可再生电力为电源的电解水制氢是一种制备高纯氢气的可持续发展路径。其中,析氢反应(HER)电催化剂的性能仍需进一步提升。阴离子空位具有增加活性位点、提升电导率以及优化中间体物质吸附能的作用,已被广泛应用于提高HER电催化剂性能。综述了近几年阴离子空位调控HER电催化剂的研究进展,以促进电解水制氢的进一步发展。重点分析了阴离子空位的制备与表征、阴离子空位对电解水析氢的影响与机制,并对阴离子空位工程提升电解水制氢催化剂性能研究的挑战进行分析与展望。
Hydrogen production by electrochemical water splitting with renewable electric power is a sustainable way to produce high-purity hydrogen.Among them,the performance of hydrogen evolution reaction(HER)electrocatalysts need to be further improved.Anion vacancy has the function of increasing the active site,improving the conductivity and optimizing the adsorption energy of intermediates,which has been widely used to improve the performance of HER electrocatalysts.We provided a brief overview on the research progress of anion vacancies regulating HER electrocatalysts to promote the development of hydrogen production by electrochemical water splitting in recent years.The preparation and characterization of anion vacancy,the influence and mechanism of anionic vacancy on HER by electrochemical water splitting were emphatically analyzed.In addition,the challenges of improving the performance of catalysts for hydrogen production from electrochemical water splitting by anionic vacancy engineering were analyzed and prospected.
