Abstract

The synthesized RuO₂/MnCo₂O_4.5 nano-heterostructure possesses dense interfaces and abundant defect structures, synergistically balancing oxygen evolution reaction (OER) activity and stability. RuO₂/MnCo₂O_4.5 exhibits a low overpotential of 190 mV at 10 mA cm^-2. The proton exchange membrane (PEM) electrolyzer assembled can operate at 200 mA cm^-2 stably for 50 h.
