Abstract The electrocatalytic oxidation of urea (UOR) at near‐theoretical potentials presents a promising approach for efficient energy conversion. A critical challenge lies in enhancing the compatibility between active sites and multiple intermediates UOR to accelerate dehydrogenation kinetics, thereby overcoming high overpotential barrier oxidation. Herein, we propose strategy enhance d–p orbital hybridization via bimetallic doping develop silver/cobalt (ACO/NS) co‐doped nickel sulfide‐based self‐supporting composite catalyst. synergistic interaction oxide sulfide heterojunction regulates hybridization, redistributes charge, optimizes adaptability Ni site levels better match various intermediates. This promotes electron coupling processes with OH⁻. Experimental results demonstrate that ACO/NS exhibits outstanding activity, achieving current density 10 mA cm −2 potential 1.04 V (versus RHE) maintaining stable activity over 168 h. Theoretical analysis combined experimental findings reveals microscopic reaction mechanism low potentials: enhanced induced by modulates adsorption strength OH* urea, accelerating kinetics work highlights feasibility through systematic modulation optimization catalysts, providing valuable insights development high‐performance catalytic systems.
