Abstract The electrochemical oxidation (EO) process has the unique advantage of in situ generation reactive oxygen species for organic synthesis and wastewater purification. However, strong binding H 2 O anode inhibits desorption species, exacerbating their peroxidation into thus weakening EO performance. In this work, an electron delocalization strategy is proposed by introducing Cu 2+ tetrahedral sites (A Td ) Co 3 4 (Cu x 3‐x to trigger super‐exchange effect ─O─Co Oh 3+ , constructing electron‐rich accelerating *OH promotion Experimental results confirm electron‐delocalized disrupts kinetic equilibrium evolution reaction balances energy barriers adsorption, dehydrogenation, over sites, realizing •OH‐mediated process. required free •OH decreases from 1.14 0.70 eV. extraordinary activity elimination multiple aromatic contaminants demonstrates feasibility practical landfill leachate treatment. This study offers in‐depth understanding active formation systems guides design superior stable electrodes efficient conversion matter.

Abstract Electrocatalysts with a hollow nanocage structure and single atoms (SAs) incorporated into layered double hydroxide (LDH) are highly significant for enhancing the efficiency of electrochemical water splitting. In this study, efficient robust electrocatalyst oxygen evolution reaction (OER) is successfully fabricated by confining Ru SAs within made NiFe LDH. An etching co‐precipitation method used making LDH nanocages integrating to produce Ru‐SAC/NiFe The architecture increases surface area available interaction enhances interface between catalyst electrolyte. synergistic electronic contact led exceptional OER performance low overpotential 196 mV at 10 mA cm ‒2 Tafel slope 40 dec⁻ 1 . Additionally, revealed long‐term stability, 120 h Density functional theory (DFT) calculations show that increased activity because they interacted more strongly intermediates caused positive changes in Gibbs free energy. goal research develop novel approach designing fabricating advanced single‐atomic materials intended use renewable energy applications.
