Electrochemical ammonia synthesis by reduction of nitrate on Au doped Cu nanowires.

ABSTRACT: Electrochemical nitrate reduction reaction (NO₃ ^-RR) to synthesize valuable ammonia (NH₃) is considered as a green and appealing alternative to enable an artificial nitrogen cycle. However, as there are other NO₃ ^-RR pathways present, selectively guiding the reaction pathway towards NH₃ is currently challenged by the lack of efficient catalyst. Here, we demonstrate a novel electrocatalyst for NO₃ ^-RR consisting of Au doped Cu nanowires on a copper foam (CF) electrode (Au-Cu NWs/CF), which delivers a remarkable NH₃ yield rate of 5336.0 ± 159.2 μg h^-1 cm^-2 and an exceptional faradaic efficiency (FE) of 84.1 ± 1.0% at -1.05 V (vs. RHE).
