Electrocatalytic urea synthesis is significantly limited by the low efficiency of C–N bond coupling between CO2 and nitrite. Here, we designed a Zn Ti bimetallic active site catalyst anchoring TiO2 on surface ZnO developed new NF@CoMn2O4@ZnO-TiO2 electrocatalyst with high resistance to deactivation. The Co3+/Mn3+-Mn4+ solid oxide pairs in maintain their stability extracting accumulated electrons around Zn2+ Ti4+ through strong electronic interactions. sites can efficiently catalyze reduction *CO, while NO2– *NH2 intermediate product. proximity shortens distance *CO intermediates, facilitating efficient electrocatalytic urea. DFT calculations indicate that ΔG required for adsorbed short-range CoMn2O4@ZnO-TiO2 lower compared CoMn2O4@ZnO ZnO. This results remarkably Faradaic 61.18% at −0.6 V vs RHE NF@CoMn2O4@ZnO-TiO2. work provides pathway achieving synergistic catalysis reactions different metal catalytic sites.

Urea electrosynthesis from the coelectrolysis of NO3– and CO2 (UENC) presents a fascinating approach for simultaneously migrating pollutants producing valuable urea. In this study, isolated Rh-alloyed copper (Rh1Cu) is explored as highly active selective catalyst toward UENC. Combined in situ spectroscopic analysis theoretical calculations reveal relay catalysis Rh1 site Cu to promote UENC energetics, which activates form *NH2 while *CO. The formed *CO then migrated substrate nearby site, promotes C–N coupling urea formation. Prominently, Rh1Cu achieves an exceptional performance flow cell, exhibiting highest urea-Faradaic efficiency 67.10% yield rate 50.36 mmol h–1 g–1 at −0.6 V versus RHE.
