Electroreduction of Nitrite to Ammonia Over Ni₁Ru Single‐Atom Alloys

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 34(3)

Published: Oct. 3, 2023

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.

Electroreduction of Nitrite to Ammonia over a Cobalt Single-Atom Catalyst

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(7), P. 2783 - 2789

Published: Feb. 2, 2024

Electrochemical nitrite-to-ammonia reduction (NO2RR) holds great promise for converting harmful NO2– into valuable NH3. Herein, we develop Co single atoms dispersed on a C3N4 substrate (Co1/C3N4) as an efficient catalyst toward the NO2RR. Experimental and theoretical investigations reveal that single-atom sites can effectively active optimize formation energy of key *NOH intermediate to promote → NH3 energetics. Remarkably, Co1/C3N4 equipped in flow cell delivers exceptional NH3–Faradaic efficiency 97.9% yield rate 1080.3 μmol h–1cm–2 at industrial-level current density 355 mA cm–2, along with long-term durability 100 h electrolysis, showing considerable potential practical electrosynthesis.
