Electrocatalytic NO reduction to NH3 (NORR) offers a prospective method for removing hazardous and producing valuable simultaneously. Herein, we demonstrate that atomically dispersed W on Pd metallene (W1Pd) can be an efficient robust NORR catalyst. Atomic coordination characterizations unravel single atoms exist as W1–O3 moieties bonded metallene. In situ spectroscopic measurements theoretical calculations reveal the synergistic cascade effect of promote energetics W1Pd, in which activation hydrogenation occur W1–O3, while dissociates H2O donates protons required NH3. Consequently, W1Pd exhibits yield rate 758.5 μmol h–1 cm–2 with NH3-Faradaic efficiency 91.3% flow cell (272.1 93.7% H-type cells), ranking almost highest performance among all reported catalysts.

Abstract Electroreduction of nitrite to ammonia (NO 2 RR) holds great promise for concurrently achieving efficient NH 3 electrosynthesis and wastewater purification. This study first develops Ni 1 Ru single‐atom alloys as an robust NO RR catalyst. Extensive experiments theoretical computations reveal that isolated atoms electronically couple their adjacent render with high thermodynamic stability, boosted − ‐to‐NH hydrogenation energetics suppressed hydrogen evolution. As a result, assembled in flow cell shows exceptional yield rate 37.5 mg h −1 cm −2 ‐Faradaic efficiency 93.9% at current density 312.3 mA , representing one the highest performances ever reported.

Palladium phosphides are explored as efficient catalysts for the electrocatalytic reduction of nitrate to ammonia (NRA). The PdP2 nanoparticles on reduced graphene oxide exhibit maximum NH3 Faradaic efficiency 98.2% with a corresponding yield rate 7.6 mg h–1 cm–2 at −0.6 V (RHE). Theoretical calculations reveal that (011) surface can not only effectively activate and hydrogenate NO3– via NOH pathway but also retard H adsorption inhibit competitive hydrogen evolution reaction.
