摘要

Herein, we have developed a functionally integrated strategy that replaces water with much readily oxidized urea to promote the electrochemical N-2 fixation. A durable robust electrocatalyst, a MOF-driven C, N-codoped nanoarray grown on nickel foam, namely CuO/Cu2O@CD-CN/NiF, serves as both the cathode and anode for the N-2 reduction and urea oxidation. It is significant that an NH3 yield rate of 102.2 mu g h(-1) cm(-2) and a faradaic efficiency of 23.9% were obtained, significantly exceeding those of its urea-free counterpart. This research not only provides value to the future artificial nitrogen fixation to ammonia but also opens up new avenues for the replacement of the sluggish oxygen evolution reaction (OER) for energy-efficient NH3 generation.
