High-Entropy Alloys as a Platform for Catalysis: Progress, Challenges, and Opportunities

High-entropy alloys (HEAs), which are defined as near-equimolar alloys of five or more elements, are attracting ever increasing attention because of the unique properties in a variety of applications. Recently, HEAs have already exhibited remarkable catalytic performance toward several thermal-driven and electrocatalytic reactions. HEAs not only regulate the electronic and geometric structures to a large degree but also serve as a platform to construct catalysts with unexpected performance. Herein, recent advances regarding HEA-based catalysis are systematically summarized, with a special focus on the synthetic methods for HEA-based catalysts, catalytic performance, and mechanistic understanding. Moreover, the…
