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⁺. This two-step process can produce ammonium with faradaic efficiency of up to 7% and yield rate up to 66 nmol s⁻¹ cm⁻².

在接近环境温度下通过镁基电化学过程将氮还原为铵


锂介导的氮还原使得氨的实际合成成为可能，但其能量效率受到锂 ^0/+ 氧化还原电位的限制。为了改善这一点，需要具有更正电势的介体，例如 Mg ^0/2+ 。在此，我们证明电沉积的 Mg ⁰ 在接近环境温度下与 N ₂ 发生反应，所得材料可以转化为 NH ₄ < b5> 。该两步法可生产铵，法拉第效率高达 7%，产率高达 66 nmol s ⁻¹ cm ⁻² 。
