Selective electrocatalytic conversion of nitric oxide (NO) to high-value chemicals has gained significant attention due to the urgent need for NO removal and the environmental impact of the nitrogen cycle imbalance. This review summarizes recent advancements in the electrocatalytic conversion of NO to valuable nitrogen-containing chemicals, focusing on catalyst design, electrolyte composition, mass transfer, and adsorption energies of key intermediates. It explores the synergistic electrochemical co-electrolysis of NO with carbon sources to synthesize chemicals with C–N bonds, providing insights into reaction pathways and mechanisms. The review highlights the potential of electrocatalytic technology to selectively convert NO into high-value chemicals under mild conditions, offering sustainable alternatives to traditional methods like selective catalytic reduction (SCR). Recent studies emphasize the development of efficient catalysts, such as Cu, hcp-Co, and CuFe DS/NC, for ammonia synthesis, hydroxylamine production, oxime formation, and amino acid synthesis. These approaches demonstrate high selectivity, efficiency, and environmental benefits. Additionally, the review discusses the electrocatalytic oxidation of NO and organic molecules, which can reduce energy consumption and catalyst costs. Overall, the review underscores the importance of electrocatalytic NO conversion in promoting nitrogen cycle balance and sustainable chemical production.Selective electrocatalytic conversion of nitric oxide (NO) to high-value chemicals has gained significant attention due to the urgent need for NO removal and the environmental impact of the nitrogen cycle imbalance.
