Abstract
Abstract Electrochemical reduction of nitrate (NO 3 RR) holds great promise for environmentally friendly ammonia production. Tandem catalysis is a promising strategy for boosting the NO 3 RR and inhibiting side effects, but it is still challenged by lacking well‐designed catalysts to drive this catalytic process. Herein, the study develops the CuCo branched nanowires (CuCo NW) catalyst, which efficiently converts NO 3 − to NH 3 on Co (111) and Cu (111) crystal facets through a tandem catalysis mechanism. The in situ grown CuCo NW on Cu foam demonstrates a remarkable Faraday efficiency of 90.3% at 1.0 A cm −2 and maintains stable operation for 200 h at 100 and 200 mA cm −2 in a flow reactor. Density functional…
