Copper nanocenters embedded in tungsten oxide (WO₃) nanowires demonstrate significant electrocatalytic activity for the reduction of nitrates and nitrites in acidic environments. Characterization indicates successful incorporation of copper active sites into the WO₃ structure.
The Cu-WO₃ catalyst effectively converts nitrates into ammonia while avoiding hydrazine formation and displays strong resistance to competing hydrogen evolution, achieving high ammonia production rates. It also performs well in reducing other inert molecules, including oxygen, carbon dioxide, and bromates.
