Nitrogenous Intermediates in NOx‐involved Electrocatalytic Reactions

Chemical manufacturing utilizing renewable sources and energy emerges as a promising path towards sustainability and carbon neutrality. The electrocatalytic reactions involving nitrogen oxides (NOx) offered a potential strategy for synthesizing various nitrogenous chemicals. However, it is currently hindered by low selectivity/efficiency and limited reaction pathways, mainly due to the difficulties in controllable generation and utilization of nitrogenous intermediates. In this minireview, focusing on nitrogenous intermediates in NOx‐involved electrocatalytic reactions, we discuss newly developed methodologies for studying and controlling the generation, conversion, and utilizing of nitrogenous intermediates, which enable recent developments in NOx‐involved electrocatalytic reactions that yield various products, including ammonia (NH3), organonitrogen molecules, and nitrogenous compounds exhibiting unconventional oxidation states. Furthermore, we also make an outlook to highlight future directions in the emerging field of NOx‐involved electrocatalytic reactions. The rapidly evolving field of NOx‐involved electrocatalysis encompasses various processes, ranging from green NH3 synthesis and the construction of C−N bonds with small molecules to the synthesis of nitrogenous compounds with unconventional oxidation states. The review aims to provide insights into recent progress, research methodologies, and prospective avenues for the regulated generation and in situ utilization of nitrogenous intermediates.
