Carbonization (Argon atmosphere, 900 °C, 2 h) of heteroatom-enriched pyridine-bridged inorganic–organic hybrid material (HPHM) resulted in the formation a high specific surface area (SABET 1080 m2 g–1) carbonaceous designated as HPHMC900. The HPHMC900 serves an effective electrocatalyst for reduction nitrate aqueous environment to ammonia (NO3RR). Importantly, demonstrated fast kinetics NO3RR with low Tafel slope 70 mV decade–1.
