Abstract Electrocatalytic reduction of nitric oxide (NO) to ammonia (NH 3 ) represents a potential solution for improving the disrupted nitrogen cycle balance. Unfortunately, designing efficient electrocatalysts NO reaction (NORR) remains notable challenge, especially at low concentrations. Herein, displacement‐alloying strategy is reported successfully induce phase transition Co nanoparticles supported on carbon nanosheets from face‐centered cubic (fcc) hexagonal close‐packed (hcp) structure through Ru incorporation. The obtained RuCo alloy with hcp (hcp‐RuCo) exhibits apparent NORR activity record‐high Faraday efficiency 99.2% and an NH yield 77.76 µg h −1 mg cat −0.1 V versus reversible hydrogen electrode concentration 1 vol %, surpassing fcc most catalysts. Density functional theory calculations reveal that excellent hcp‐RuCo can be attributed optimized electronic site lowered energy barrier rate‐determining step transition. Furthermore, assembled Zn‐NO battery using as cathode achieves power density 2.33 mW cm −2 45.94 . This work provides promising research perspective low‐concentration conversion.
