Abstract Electrocatalytic nitrate (NO 3 − ) reduction to ammonia (NH is a green and efficient NH synthesis technology. Metallic silver (Ag) one of the well‐known electrocatalysts for NO reduction. However, under alkaline conditions, its poor water‐splitting ability fails provide sufficient protonic hydrogen required synthesis, resulting in low selectivity. Additionally, metal catalysts are prone leaching oxidation during electrocatalysis, stability. Herein, cobalt (Co) into Ag (CoAg) catalyst doped, which not only increases selectivity by 34.4%, but also reduces potential 0.1 V. Meanwhile, reduced graphene oxide (rGO) as protective “armor” used encapsulate CoAg (rGO 2.92 @CoAg). The rGO @CoAg shows excellent stability over 300 hours (h) continuous reaction. Co contents after tests decreases 4.3% 3.1%, respectively, much lower than those without (90.8%, 52.6%). Moreover, high Faradaic efficiency (99.3%) yield rate (1.47 mmol h −1 cm −2 ). Therefore, performance strong obtained doping coating, provides theoretical basis practical industrial application.
