Abstract

Pt/TiO₂-Cu₂O photocatalysts were prepared in the experiments. For these complex oxides, morphology, structure, composition and optical properties were investigated by HRTEM, XRD, ICP and UV-visible techniques, respectively. In addition, in the absence of oxygen, the photocatalytic generation of H₂ from methanol over Pt/TiO₂-Cu₂O under visible light was studied and the effects of Pt content and composition of catalyst on photocatalytic activity were elucidated. The result showed Pt was deposited on the surface of TiO₂-Cu₂O in a clustered manner with particle size of 5-20 nm. When Pt content reached 1 wt. %, such catalyst exhibited highest photocatalytic activity. After the catalyst of 1 % Pt/5 % TiO₂-Cu₂O used for 7 times, the photocatalytic activity in the generation from aqueous methanol of hydrogen remained relatively stable. The catalyst of Pt/TiO₂-Cu₂O photocatalytic generation of hydrogen from methanol solution achieved through the photo-generated electron of e^- reduction of H₂O to produce H₂. As a result, 327 μmol H₂ was obtained after 3 h.
