Abstract Replacing the anodic oxygen evolution reaction with selective methanol oxidation to formic acid offers a promising route enhance paired electrochemical ammonia synthesis. However, inherent kinetic and thermodynamic disparities between cathodic reduction present significant challenges in achieving optimal system performance. Herein, we propose dual‐reaction strategy employing bifunctional Au/CoOOH nanocomposite catalysts, simultaneous NH 3 production (34.15 g) synthesis (69.65 after 24 h at 2.6 V cell voltage. Density functional theory (DFT) calculations further reveal that loading Co‐based catalysts its hybridization Au nanoparticles can effectively tune electronic configuration of Co‐O sites poison their strong adsorption capacity intermediate products, lowering energy barrier alter pathway. This work provides an atomic‐level design principle for coupled systems, demonstrating better efficiency, while co‐producing high‐value chemicals scalable green
