Abstract

The Li-mediated nitrogen reduction enables practical synthesis of ammonia, but its energy efficiency is limited by the Li^0/+ redox potential. To improve on this, a mediator with a more positive potential, like Mg^0/2+, is required. Herein, we demonstrate that electrodeposited Mg⁰ reacts with N₂ at a close-to-ambient temperature, and the resulting material can be converted into NH₄⁺.
