Abstract The arrangement of atoms in the catalyst directly impacts catalytic performance. Herein, a heteroatom doping strategy is found as an effective approach for regulation MnO 2 crystal reconstruction during oxygen evolution reaction (OER), thereby ensuring and optimizing performance catalyst. Real‐time tracking dynamic surface reveals that δ‐MnO transforms into less active γ‐MnOOH phase, while single‐atom Fe facilitates formation highly α‐MnOOH phase. asymmetric Fe─O─Mn bonds induce lattice distortions promote electron transfer from to Mn with increase 3 ⁺ content, which conducive intensifying spillover crucial factor OER activity. Theoretical calculations also demonstrate sites regulated representative can reduce energy barrier step process (the *O *OOH transition), thus significantly enhancing typical achieves successful processes through doping, holds significant implications developing new class catalysts, not limited catalysts reported this study.

Abstract The acidic oxygen evolution reaction (OER) electrocatalysts for proton exchange membrane electrolyzer (PEMWE) often face a trade‐off between activity and stability due to inherent linear relationship overoxidation of metal atoms in highly oxidative environments, while following the conventional adsorbate mechanism (AEM). Herein, favorable AEM‐derived acceptor‐electron donor (PAEDM) is proposed RuO 2 by constructing interstitial‐substitutional mixed solid solution structure (denoted as C,Ta‐RuO ), which can effectively break activity‐stability OER. In situ spectroscopy experiments theoretical calculations reveal that interstitial C acceptor reduces deprotonation energy barrier, enhancing catalytic activity, substitutional Ta electron donates electrons Ru sites via bridging oxygen, weakening Ru─O bond covalency preventing over‐oxidation surface Ru, thereby ensuring long‐term stability. Under guidance this mechanism, optimized simultaneously achieves far low overpotential (η 10 = 171 mV) ultra‐long (over 1300 h) More remarkably, homemade PEMWE using anode also shows high water splitting performance (1.63 V@1 A cm −2 ). This work supplies novel strategy guide future developments on efficient OER toward oxidation.
