Ruthenium (Ru)-based catalysts have demonstrated promising utilization potentiality to replace the much expensive iridium (Ir)-based ones for proton exchange membrane water electrolysis (PEMWE) due their high electrochemical activity and low cost. However, susceptibility of RuO2-based materials easily be oxidized high-valent soluble Ru species during oxygen evolution reaction (OER) in acid media hinders practical application, especially under current density above 500 mA cm–2. Here, a manganese-doped RuO2 catalyst with hydroxylated metal sites (i.e., H–Mn0.1Ru0.9O2) is synthesized acidic OER assisted by hydrogen peroxide, where hydroxylation results valence state below +4. The H–Mn0.1Ru0.9O2 demonstrates an overpotential 169 mV at 10 cm–2 stability over 1000 h electrolyte. A PEMWE device fabricated as anode shows 1 ∼1.65 V, along degradation continuous tens hours. Differential mass spectrometry (DEMS) theoretical calculations confirm that performs through adsorbate mechanism (AEM) pathway, synergistic effect Mn doping can effectively enhance lattice atoms.
