Abstract

High-entropy alloys (HEAs), that are composed of more than five metal elements in almost equimolar ratios, have gained considerable interest as electrocatalytic materials because of their high catalytic activity, high porosity, and excellent stability. HEAs have controllable electronic structures and geometric configurations, which give the prepared materials an unexpected catalytic activity. This review focuses on introducing the research progress on HEAs in recent years and analyses and summarises the new preparation methods, catalytic properties, and theoretical research on the materials. In addition, the opportunities for and challenges faced by HEAs as electrocatalysts are presented.
