Research progress of high-entropy alloy catalysts in water electrolysis for hydrogen production and hydrogen fuel cells
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.High-entropy 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.
