The advancement of acid-stable oxygen evolution reaction (OER) electrocatalysts is crucial for efficient hydrogen production through proton exchange membrane (PEM) water electrolysis. Unfortunately, the activity constrained by a linear scaling relationship in adsorbed mechanism, while lattice-oxygen-mediated mechanism undermines stability. Here, we propose heterogeneous dual-site oxide pathway (OPM) that avoids these limitations direct dioxygen radical coupling. A combination Lewis acid (Cr) and Ru to form solid solution oxides (Cr
