Urea synthesis <i>via</i> electrocatalytic C–N coupling of CO<sub>2</sub> and nitrate on oxygen-vacancy-rich Co<sub>3</sub>O<sub>4</sub>–CuO heterostructure nanowires
Herein, oxygen-vacancy-rich Co<sub>3</sub>O<sub>4</sub>-CuO nanowires on Cu foam (Co<sub>3</sub>O<sub>4</sub>-CuO/CF) have been prepared for urea electrosynthesis. The Co<sub>3</sub>O<sub>4</sub>-CuO heterostructure significantly boosts electron transformation and reaction kinetics, and abundant oxygen vacancies substantially facilitate the adsorption and activation of CO<sub>2</sub> and nitrate. As such, the Co<sub>3</sub>O<sub>4</sub>-CuO/CF demonstrates an impressive faradaic efficiency of 35.89% and urea yield of 1.12 mg cm<sup>-2</sup> h<sup>-1</sup>, while maintaining exceptional cycle durability.
