Abstract

Improving photocatalytic activity and stability of TiO₂/Cu ₂O composite is a challenge in generating hydrogen from water. In this paper, the TiO₂ film/Cu₂O microgrid composite was prepared via a microsphere lithography technique, which possesses a remarkable performance of producing H₂ under UV-vis light irradiation, in comparison with pure TiO₂ film, Cu₂O film and TiO ₂ film/Cu₂O film. More interesting is that in TiO ₂ film/Cu₂O microgrid, photo-corrosion of Cu₂O can be retarded. After deposition of Pt on its surface, the photocatalytic activity of TiO₂/Cu₂O microgrid in producing H₂ is improved greatly.
