Abstract Nitrate (NO 3 − ) contamination from industrial, agricultural, and anthropogenic activities poses significant risks to human health ecosystems. While traditional NO remediation methods are effective, they often generate secondary pollutants incur high costs. Electrochemical reduction (ECNR) offers a sustainable alternative, converting into environmentally benign nitrogen (N 2 or valuable ammonia (NH ). This review explores recent advancements in selective ECNR pathways for ‐to‐N ‐to‐NH conversion, focusing on mechanistic insights, electrocatalyst development, optimization strategies. Key factors influencing performance, such as electrode materials, electrolyte composition, hydrogen evolution inhibition, discussed. Additionally, the highlights role of single‐atom, bimetallic, nanostructured catalysts enhancing faradaic efficiency, total N removal, selectivity, with particular attention Pd−Cu systems. Strategies address challenges like low selectivity catalyst degradation also explored. underscores potential viable alternative energy‐intensive Haber‐Bosch process NH production, aligning global sustainability goals. Finally, we identify research gaps propose future directions improving stability, scalability technologies.
