【摘要】 氢能作为可持续发展的清洁可再生能源，受到人们高度重视。电解水制氢技术是最主要的制取氢方法，也是实现碳中和的主要途径。然而，现有电解水制氢催化剂存在电流密度小、稳定性差等问题，难以满足工业化应用的需求，因此制备高电流密度和高稳定性的电催化剂具有非常重要的意义。本文系统总结了近年来在高电流密度、高稳定性电催化剂设计、制备等方面取得的最新进展，阐述了高电流密度、催化剂稳定性对电解水制氢性能的影响。重点介绍了高电流密度条件下，具有良好稳定性催化剂的设计策略，旨在为制备性能更优异的高电流密度电催化剂提供指导。最后，讨论了高电流密度操作条件下电解水制氢存在的挑战并对未来的发展方向进行了展望。更多还原

【Abstract】 Developing hydrogen energy is of strategic significance under the background of carbon peaking and carbon neutrality as the green hydrogen is the ultimate goal of hydrogen energy development. Electrolysis is a primary option to produce hydrogen and neutralize carbon. Preparing electrocatalytic catalysts with high current density and high stability to meet the needs of industrial applications is of great significance. In this paper,the latest progress in the design of high current density and highstability electrocatalysts is systematically summarized.The effects of high current density and high stability on the hydrogen evolution performance of electrolysis are expounded. The design strategy of catalyst under the high current density and high stability conditions for hydrogen production is introduced,aiming to provide guidance for the preparation of high current density electrocatalysts with superior performance. Finally,the challenges faced with hydrogen electrolysis under operating conditions of high current density and high stability are discussed and the future development directions are prospected.更多还原
