Abstract
Abstract Oxygen evolution reactions (OER) are critical to electrochemical synthesis reactions, including hydrogen production and organic hydrogenation. However, the high cost of existing OER catalysts (primarily Ir/Ru and its derived oxides) limits their practical application for electrochemical synthesis. To develop a low‐cost, high‐efficiency alternative, we need a deeper understanding of both the mechanisms that drive OER and the relationship between the catalyst's electronic structure and active sites. Here, we summarized recent developments of catalysts, especially focusing on the electronic structure modulation strategies and their subsequent activity enhancement. Most importantly, we pointed out the study directions for further work.
