Abstract Electrochemical nitrate reduction to ammonia (eNO 3 RR) in neutral conditions is an effective and sustainable method for production while treating pollution. Nevertheless, it still faces a great challenge due the complicated multiple proton‐coupled‐electron process eNO RR. Herein, efficient heterostructure electrocatalyst Cu‐Cu 2 O/Ni P has been successfully fabricated electrosynthesis from reduction. exhibits outstanding RR performance with Faradaic efficiency (FE) as high 96.4% yield rate of 14636 µg·h −1 ·cm −2 at −1.0 V (vs RHE) 0.1 m PBS solution, which outperforms most reported electrocatalysts media. More importantly, catalyst demonstrates exceptional stability 30 consecutive electrolysis cycles durability even large current density 440 mA cm flow cell. The tandem catalysis mechanism NO − → NH by synergism two components O Ni verified experimental theoretical calculations. strong adsorption capacity can be reduced into , facilitate water splitting, promotes abundant *H production, thus boosting subsequent hydrogenation during whilst inhibiting competitive hydrogen evolution reaction (HER).

Abstract Electrocatalytic nitrate reduction to ammonia (NRA) offers an arousing route for converting widespread pollutant under mild conditions. Among other NRA catalysts, single‐atom catalyst (SAC) has emerged as a promising candidate due its numerous advantages such maximum metal‐atom‐utilization efficiency, homogeneous and tailorable active sites, which still encounters formidable challenge accelerate the kinetics simultaneously suppress competitive hydrogen evolution reaction, especially when operated in electrolytes with low concentration nitrate. Herein, general strategy is reported prepare defect‐enriched coordination polymer catalysts featuring well‐defined unsaturated metal can exhibit exceptional performance even at surpass SACs toward catalysis. Taking cobalt (Co) example, Co‐based polymers (d‐CoCP) counterpart CoCP without defects are investigated proof‐of‐concept study. Both experimental theoretical results elucidate that elaborately‐engineered d‐CoCP markedly decrease thermodynamic barrier reducing *NO *HNO rate‐limiting step along pathway, thus accelerating adsorption of promoting kinetics.
