Emerging high-entropy coordination compounds and their derivatives for energy application

Abstract

High-entropy materials (HEMs) have attracted great attention due to the distinctive designing concept and unique properties which are expected to make new advances in several energy conversion and storage technologies. Recently, the library of HEMs was further expanded, and the concept of high entropy was introduced into some coordination compounds such as metal–organic frameworks (MOFs), metal-glycerate/metal-glycerolates as well as metal-polyphenol coordination polymers which may facilitate new opportunities for targeted applications. In fact, high-entropy coordination compounds (HE-CCs) have been considered a new family for the next generation of electrode materials in energy technologies. Herein, the progress of the recently developed HE-CCs, including synthesis strategies and their performances for catalyzing the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in water electrolysis as well as electrochemical performances in rechargeable batteries are highlighted. Besides, we describe effective and promising strategies for rationally designing HEMs derived from HE-CCs. Finally, an outlook, prospects and Quo Vadis of this field provides guidance for the development of new and improved HE-CCs and their derivatives to pave the way for future advancements.
