Abstract

The electrochemical oxidation of ammonia (NH₃) enables decentralized small-scale synthesis of nitrate (NO₃^-) and nitrite (NO₂^-) under ambient conditions by directly utilizing renewable energy. Yet, their electrosynthesis has been restricted to aqueous media and low ammonia concentrations. For the first time, we demonstrate here a strategy enabling the direct electrooxidation of liquefied NH₃ to NO₃^- and NO₂^- by using molecular oxygen, achieving combined Faraday efficiencies above 40%.

在液化氨中通过阴极氧活化电化学合成亚硝酸盐和硝酸盐。

氨（NH3）的电化学氧化可直接利用可再生能源，在环境条件下分散地小规模合成硝酸盐（NO3-）和亚硝酸盐（NO2-）。然而，它们的电合成一直局限于水介质和低氨浓度。我们在此首次展示了一种利用分子氧将液化 NH3 直接电氧化成 NO3- 和 NO2-的策略，其综合法拉第效率超过 40%。
