摘要

在Cu泡沫上制备了富氧空位的Co3O4-CuO纳米线（Co3O4-CuO/CF），用于尿素电合成。Co3O4-CuO异质结构显著促进了电子转化和反应动力学，丰富的氧空位大大促进了CO₂和硝酸盐的吸附和活化。因此，Co3O4-CuO/CF表现出令人印象深刻的法拉第效率35.89%和尿素产率1.12 mg cm−2 h−1，同时保持了出色的循环耐久性。

Urea synthesis via electrocatalytic C–N coupling of CO2 and nitrate on oxygen-vacancy-rich Co3O4–CuO heterostructure nanowires†

Herein, oxygen-vacancy-rich Co₃O₄–CuO nanowires on Cu foam (Co₃O₄–CuO/CF) have been prepared for urea electrosynthesis. The Co₃O₄–CuO heterostructure significantly boosts electron transformation and reaction kinetics, and abundant oxygen vacancies substantially facilitate the adsorption and activation of CO₂ and nitrate. As such, the Co₃O₄–CuO/CF demonstrates an impressive faradaic efficiency of 35.89% and urea yield of 1.12 mg cm⁻² h⁻¹, while maintaining exceptional cycle durability.
