This cover introduces the research progress of Ru-based catalysts for acid water electrolytic anode. Hydrogen production by proton exchange membrane water electrolyzer (PEMWE) is a promising method to provide clean energy. The slow kinetics of anodic oxygen evolution (OER) is considered to be a key obstacle to its conversion efficiency. Compared with Ir-based catalysts, Ru-based catalysts have higher catalytic activity and lower price, which has become the main research direction to reduce the cost of PEMWE. This review summarizes the current factors affecting the performance of Ru-based catalysts and the improvement methods, including electronic structure, defects, metal-oxygen covalency.
