Abstract Emissions of nitrogen oxide (NO x ) species and NO 2 nitrate/nitrite − , such as 3 have led to serious water pollution climate challenges. How remove these wastes is a global problem that urgently needs be addressed. As reported, electrochemical catalytic technology under ambient conditions great interest for /NO removal. Additionally, the in situ utilization surface‐adsorbed nucleophilic intermediates generated from reduction can provide sustainable strategy building C−N bonds, upgrading waste into value‐added organic products, amines, oximes, amides, amino acids, while remediating environment. This review summarizes most recent progress construction compounds by coupling reactions with inorganic/organic substrates, focuses on understanding adsorption–transformation mechanism during process, discusses multiple side complex pathways. Important strategies, coupled system development catalyst preparation, are also presented broaden range improve yields. Finally, few key challenges future research directions efficient low‐cost processes discussed.

Electrocatalytic nitrate reduction reaction (ENO3RR) to NH3 provides an appealing route valorize pollutants needed close the nitrogen cycle. The development of metal-free carbon catalysts with high stability and well-developed active sites for ENO3RR is highly desirable, while role structural defects (such as vacancies or functional groups) on electrosynthesis not fully understood. Herein, we developed a group carbon-based regulated quaternary-N N vacancies, effect dual defect process was systematically investigated. as-prepared NHC-1000 catalyst atomic-level engineered exhibited Faradaic efficiency 91.2% associated yield rate 2.6 mmol h–1 g–1 at –0.5 V (vs RHE), better than most reported electrocatalysts. According structure characterization theoretical calculations, yielded dependent defective involved catalytic sites. moiety facilitated potential-determining step *NO protonation *NHO further contributed formation *NH2 intermediates by synergistic action N-vacancies, which enhanced NO3– activity effectively. This work fundamental principle deeper understanding designing advanced engineering applied in
