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.

Abstract Nitrite (NO 2 − ) and hydrazine (N H 4 are common N‐pollutants in groundwater. The electrochemical method can realize the treatment of synthesis energy substance ammonia (NH 3 ). Designing synthesizing efficient electrocatalysts is great significance. Herein, ultrathin Co 0.5 NiS nanosheets attached on nickel foam (Co NiS‐NSs/NF) synthesized via cyanogel‐NaBH hydrolysis process succedent sulfurization approach. Owing to nanosheet structure interaction between Ni Co, NiS‐NSs/NF exhibits high activity for NO reduction reaction RR), which Faraday efficiency 92.2% NH yield 0.25 mmol h −1 cm −2 at −0.15 V potential. Meanwhile, also displays remarkable N oxidation KOH electrolyte. Therefore, a symmetrical NiS‐NSs/NF||Co electrolyzer assembled, only needs operating voltage 0.36 reach 10 mA ‐to‐NH conversion presence . This work reports promising strategy production small N‐pollutants.
