There is a growing interest in using ammonia as a liquid carrier of hydrogen for energy applications. Currently, ammonia is produced industrially by the Haber‐Bosch process, which requires high temperature and high pressure. In contrast, bacteria have naturally evolved an enzyme known as nitrogenase, that is capable of producing ammonia and hydrogen at ambient temperature and pressure. Therefore, nitrogenases are attractive as a potentially more efficient means to produce ammonia via harnessing the unique properties of this enzyme. In recent years, exciting progress has been made in bioelectrocatalysis using nitrogenases to produce ammonia. Here, the prospects for developing biological ammonia production are outlined, key advances in bioelectrocatalysis by nitrogenases are highlighted, and possible solutions to the obstacles faced in realising this goal are discussed.

硝酸酶生物电催化生产绿色氨的见解。

使用氨作为氢的液体载体用于能源应用的兴趣日益增长。目前，氨是通过哈伯-博世（Haber-Bosch）工艺在工业上生产的，这需要高温和高压。相比之下，细菌自然进化出一种称为氮酶的酶，该酶能够在环境温度和压力下产生氨和氢。因此，通过利用这种酶的独特性质，将其作为生产氨的潜在更有效的手段具有吸引力。近年来，在使用氮酶生产氨的生物电催化中取得了令人兴奋的进展。在此，概述了生物氨生产的发展前景，并突出了氮酶在生物电催化方面的关键进展，
