Abstract The nitrate electroreduction reaction (NO 3 RR) offers an eco‐friendly alternative to the Haber–Bosch technology for ammonia (NH ) synthesis. However, complex process and diverse products make efficient NH synthesis challenging. Therefore, rational design preparation of highly electrocatalysts are crucial NO RR. Herein, ultrathin copper‐nickel oxide (Cu‐NiO) nanosheets (Cu‐NiO UTNSs) synthesized via cyanogel‐NaBH 4 hydrolysis‐reduction method, which applied cathodic RR ‐assisted with anodic sulfur ion (S 2− oxidation (SOR) in electrolyzer. nanosheet structure, interaction between NiO Cu, formation oxygen vacancy contribute generating rich active sites, regulating electronic improving substance adsorption. Thus, Cu‐NiO UTNSs exhibit excellent electrocatalytic performance SOR. As a bifunctional UTNSs||Cu‐NiO electrolyzer, it can reach 10 mA cm −1 at only 0.1 V − ‐to‐NH conversion cathode S ‐to‐S 8 anode. This work provides promising approach producing value‐added chemicals low electrolysis voltage strategy pollutant treatment.
