Efficient ammonia synthesis via electroreduction of nitrite using single-atom Ru-doped Cu nanowire arrays

Here, we report the highly active and selective electrocatalytic reduction of NO ions to value-added NH over a single-atom Ru-modified Cu nanowire array on three-dimensional copper foam (Ru-Cu NW/CF) under ambient conditions. The obtained Ru-Cu NW/CF catalyst exhibited a maximum faradaic efficiency...

Zusammenfassung:Here, we report the highly active and selective electrocatalytic reduction of NO ions to value-added NH over a single-atom Ru-modified Cu nanowire array on three-dimensional copper foam (Ru-Cu NW/CF) under ambient conditions. The obtained Ru-Cu NW/CF catalyst exhibited a maximum faradaic efficiency of 94.1% and an NH yield up to 211.73 mg h cm (0.732 mmol h cm ), which was approximately five times higher than that of the Cu NW/CF catalyst.
