High-Entropy Coordination Compounds and Their Derivatives as Electrocatalytic Materials

High-entropy materials (HEMs) have attracted global research interest due to their distinctive design concept and unique properties. They are expected to make new progress in developing high-performance electrocatalysts, thus achieving efficient energy conversion and storage technologies. More recently, the repertoire of HEMs has undergone further expansion, with the high entropy concept making its way into various coordination compounds (HE-CCs), including mainly metal–organic frameworks and Prussian blue analogues. Additionally, other multielement systems, such as metal-glycerolates and metal-polyphenol coordination polymers, have been documented in the literature. This development opens up new avenues for exploring electrocatalytic applications. In this chapter, the progress on HE-CCs and their derivatives, including effective and promising electrode design strategies and their electrocatalytic performances for the hydrogen evolution reaction (HER), oxygen evolution reaction (OER) in water electrolysis, oxygen reduction reaction (ORR), urea oxidation reaction (UOR), and catalytic activity in Li–S batteries are highlighted. Finally, the conclusion and prospects outlined here can serve as guiding principles for advancing novel and enhanced HE-CCs and their derivatives, thus paving the path for future progress.
