High-quality Cu2O nanowire (NW) photocathode was successfully fabricated upon annealing Cu(OH)2 NW precursor. The precursor was prepared via a wet chemical oxidation method [Cu foil + (NH4)2S2O8 + NaOH] which is always accompanied with unfavourable nanostructured CuO. However, the present study has...
