High-entropy catalysts for electrochemical water-electrolysis of hydrogen evolution and oxygen evolution reactions

扫码查看
High entropy materials(HEMs)have develop-ed rapidly in the field of electrocatalytic water-electrol-ysis for oxygen evolution reaction(OER)and hydrogen evolution reaction(HER)due to their unique properties.In particular,HEM catalysts are composed of many elements.Therefore,they have rich active sites and enhanced entropy stability relative to single atoms.In this paper,the preparation strategies and applications of HEM catalysts in electrochemical water-electrolysis are reviewed to explore the stabilization of HEMs and their catalytic mechanisms as well as their application in support green hydrogen production.First,the concept and four characteristics of HEMs are introduced based on entropy and composition.Then,synthetic strategies of HEM catalysts are systema-tically reviewed in terms of the categories of bottom-up and top-down.The application of HEMs as catalysts for electrochemical water-electrolysis in recent years is emp-hatically discussed,and the mechanisms of improving the performance of electrocatalysis is expounded by com-bining theoretical calculation technology and ex-situ/in situ characterization experiments.Finally,the application prospect of HEMs is proposed to conquer the challenges in HEM catalyst fabrications and applications.
