Electrochemical Synthesis of Nitrite and Nitrate via Cathodic Oxygen Activation in Liquefied Ammonia

Year: 2024

Type: article

Abstract: High Resolution Image Download MS PowerPoint Slide The electrochemical oxidation of ammonia (NH 3 ) enables decentralized small-scale synthesis of nitrate (NO 3 – ) and nitrite (NO 2 – ) 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 3 to NO 3 – and NO 2 – by using molecular oxygen, achieving combined Faraday efficiencies above 40%.
