Studies on the substrate-dependent photocatalytic properties of Cu₂O heterojunctions.

ABSTRACT: Cu₂O is a promising material for photocatalysis because of its absorption ability in the ultraviolet (UV)-visible light range. Cu₂O deposited on conductive Ti and fluorine-doped tin oxide (FTO) substrates behaves as a photocathode. Cu₂O deposited on an n-type semiconductor such as TiO₂ nanotube arrays (TNA)/Ti behaves as a photoanode and has demonstrated better photocatalytic activity than that of TNA/Ti. The substrate-dependent photocatalytic properties of Cu₂O heterojunctions are not well studied. In this work, the photocatalytic properties of a Cu₂O/TNA/Ti junction as a photoanode and of Cu₂O/Ti and Cu₂O/FTO junctions as photocathodes without bias were systematically studied to understand their perfo
