The electrocatalytic urea oxidation reaction (UOR) is a promising approach to lowering the energy barrier of anode half-reaction in water splitting for energy-efficient hydrogen production and remove excess from blood or dialysis fluid. However, sluggish kinetics large overpotential caused by scaling relationships significantly limit development UOR technology. Herein, bifunctional amorphous M-CoS (M = Zr, Cu, Mn, Fe) nanosheets were synthesized via one-step electrodeposition process. Among them, Zr-CoS exhibited exceptional performance, achieving 10 mA cm-2 at an 1.26 V, outperforming recently reported catalysts, while CoS demonstrated evolution impressively low -175 mV. Density functional theory calculations revealed that doped Cu Zr ions migrated adsorption sites N atoms before after C-N cleavage, breaking limitation relationships. Meanwhile, cleavage step showed good linear relationship with variation integrated crystal orbital Hamilton population (ΔICOHP), indicating ΔICOHP was descriptor evaluate performances. This work not only emphasized outstanding performances but also offered innovative insights into role metal sulfides UOR.
