1 Introduction Water electrolysis hydrogen production has the advantages of cleanliness and efficiency, and is of great importance for the future energy economy.[1] The development of electrolytic water catalysts adapted to large-scale industrial applications is essential but challenging.[2] Currently, the commercially available catalysts are IrO2 for oxygen evolution reaction (OER) and Pt/C for hydrogen evolution reaction (HER), but they are limited by high costs and low stability.[3] In...
