Recent Development and Future Perspectives of High Entropy Alloys for Catalysts

Abstract High entropy alloys (HEAs) are composed of five or more metal elements with similar proportions. Due to the electronic structure among metal elements, they have abundant active sites and have good catalytic activity and stability as materials. Therefore, they have great promise in electrochemical energy storage and electrocatalysis. This paper reviews the preparation and characterization methods of HEAs, and the applications of HEAs in catalysis, especially the contribution in lithium‐sulfur batteries, but also in Electrolyzed water and other energy storage materials. The challenges of HEAs in catalysis and their future developments are also presented.
