Pursuing highly active and stable Ru-based catalysts for the oxygen evolution reaction (OER) under acidic conditions is important in advancing proton exchange membrane (PEM) water electrolyzers. Unfortunately, inadequate stability, especially a large current density of catalysts, still hinders its practical application. Herein, we report La doping strategy that simultaneously enhances both OER activity stability RuO2 media. The introduction into induces tensile strain, which effectively weakens covalency Ru–O bonds. This structural modification significantly inhibits Ru dissolution, thereby substantially enhancing RuO2. Meanwhile, modulates electronic structure optimizes adsorption energy intermediates, electrocatalytic activity. Notably, optimized La0.05-RuO2 electrocatalyst presents an excellent performance 0.5 M H2SO4 electrolyte, delivers low overpotential 190 mV at 10 mA cm–2 sustains 150 h without obvious decay 50 cm–2. More importantly, PEM electrolyzer constructed by using our as anode catalyst, acquires 200 1 A cm–2, highlighting strong potential industrial applications. work sheds new light on designing high-performance toward
