Abstract

The electrochemical oxidation of ammonia (NH) enables decentralized small-scale synthesis of nitrate (NO) and nitrite (NO) 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 NH to NO and NO by using molecular oxygen, achieving combined Faraday efficiencies above 40%.

摘要

氨（NH₃）的电化学氧化能够在环境条件下通过直接利用可再生能源实现硝酸盐（NO₃⁻）和亚硝酸盐（NO₂⁻）的分散式小规模合成。然而，它们的电合成一直局限于水性介质和低氨浓度。在此，我们首次展示了一种策略，即利用分子氧将液化NH₃直接电氧化为NO₃⁻和NO₂⁻，实现了超过40%的综合法拉第效率。
