Abstract
Abstract Ruthenium is considered one of the most promising alternatives to iridium as an anode electrocatalyst for proton exchange membrane water electrolysis (PEMWE). However, Ru‐based electrocatalysts suffer from poor stability, primarily due to structural collapse under the harsh acidic conditions of oxygen evolution reaction (OER). Here, a design strategy is introduced that significantly enhances both the stability and activity of RuO 2 by switching the catalytic mechanism from the adsorbate evolution mechanism (AEM) to the oxide pathway mechanism (OPM). This is achieved through lattice distortion engineering using a co‐doping strategy involving large‐radius ions (Na⁺ and Hf 4+ ). The incorporation of Na +…
