Abstract

Abstract Although RuO 2 ‐based electrocatalysts have been widely studied for acidic oxygen evolution reaction (OER), triggering the conventional adsorbate evolution mechanism to suppress kinetically favorable lattice oxygen mechanism (LOM) pathway at the expense of activity is the state‐of‐the‐art strategy. To date, approaches to simultaneously achieve remarkable activity and stability of RuO 2 ‐based electrocatalysts through the kinetically favorable LOM pathway toward acidic OER are still elusive. Herein, we report that RuS 0.45 O x catalyst with the synergetic regulation of asymmetric S–Ru–O microstructure and Ru–SO 4 local environments can simultaneously boost the lattice‐oxygen‐mediated OER activity and…
