Abstract

TiO₂ microspheres were synthesized by hydrothermal reaction using Ti(OBu)₄ as the precursor. In order to enhance the efficiency of water splitting by the TiO₂ microspheres, Pt-modified TiO ₂ microspheres were prepared by the impregnation-reduction method. The diameter of TiO₂ microspheres is around 5-10 μm. The photocatalytic performances of the catalysts were measured by hydrogen generation from a mixture of water and methanol under UV light irradiation. The photocatalytic activity of the TiO₂ microspheres was remarkably enhanced by loading Pt. The optimal Pt loading is 1.2 wt%. Pt/TiO₂ microspheres exhibit about 125 times greater H₂ production rate than the unmodified TiO₂ microspheres. The effect of calcination temperature on photocatalytic activity of the TiO₂ microspheres was also investigated.
