Hydrogen energy, with its high energy density and diverse application scenarios, is an important part of the renewable energy system. Hydrogen production from water electrolysis technology achieves efficient conversion of hydrogen energy through electrochemical dissociation of water molecules. However, precious metal catalysts (Pt/C, IrO2, etc.) for cathodic hydrogen evolution reaction (HER) are expensive and scarce. Therefore, recent research focuses on the development of cost-effective non-precious metal-based electrocatalysts. In this work, a heterostructured MoO2/Ni electrocatalysts (NM600...
