The proton exchange membrane (PEM) water hydrolyzer is crucial to promoting the sustainable development of hydrogen energy and facilitating large-scale transformation. However, achieving sustained stable oxygen evolution reaction (OER) in acidic solutions presents a significant challenge for noniridium based electrocatalysts. Herein, we develop Co3O4-supported RuO2 electrocatalyst with optimized catalyst–support interface interactions breaking activity–stability trade-off relationship OER. Through detailed electrochemical experiments characterization analysis, demonstrate that crystal growth Co3O4 support can be precisely regulated by modifying ligand layer-confined domain cobalt-based metal–organic frameworks (Co-MOF) precursor, thereby optimizing RuO2/Co3O4 interface. Due weakened self-sacrifice effect Co3O4, active heterogeneous electron interaction impeccable coating effect, OER stability RuO2/Co3O4–B3DC significantly improved compared while preserving intrinsic activity. Theoretical modeling suggests formation optimizes adsorption intermediates, process. Additionally, anode demonstrates promising potential application PEM electrolyzers variety renewable energy-driven electrolytic cells.

Abstract The electrocatalytic performance of single‐site catalysts (SSCs) is closely correlated with the electronic structure metal atoms. Herein we construct a series Pt SSCs on heteroatom‐doped hierarchical carbon nanocages, which exhibit increasing hydrogen evolution reaction (HER) activities along S‐doped, P‐doped, undoped and N‐doped supports.
