摘要
发展绿色氢能和氢燃料电池被视为实现我国双碳目标的重要抓手,需要开发高活性、高稳定性且廉价的电催化剂。高熵合金(HEA)因其表面复杂性和成分可调性,为构建高性能的催化活性位点提供了可能。通过组分选择及调控,有望实现针对不同电化学反应的表面活性位点的优化,进而大幅度提升HEA催化剂性能。近年来,HEA材料在电催化领域受到了广泛关注,有望成为理想的新型电催化剂。介绍了HEA催化剂的主要合成方法,总结了HEA催化剂在电解水制氢和氢燃料电池中的最新应用,展望了HEA催化剂的发展趋势及面临的问题,以期为HEA催化剂的设计和制备提供参考。
Developing green hydrogen energy and hydrogen fuel cells is considered an important approach to achieving China's carbon peaking and carbon neutrality goals,which requires the development of highly active,stable and cost-effective electrocatalysts.Highentropy alloy(HEA),with their surface complexity and tunable compositions,offers potential for creating high-performance catalytic active sites.By selecting and regulating components,it is possible to optimize surface active sites for various electrochemical reactions,thereby significantly enhancing the performance of HEA catalysts.In recent years,HEA has garnered widespread attention in the field of electrocatalysis and is expected to become the ideal new electrocatalyst.The main synthesis methods of HEA catalysts were introduced,the latest applications of HEA catalysts in water electrolysis for hydrogen production and hydrogen fuel cells were summarized,and the development trends and challenges faced by HEA catalysts were discussed.The aim is to provide a reference for the design and preparation of HEA catalysts.
