摘要：

Three forms of TiO2, commercial TiO2 powder, hydrogen titanate nanotubes obtained by hydrothermal treatment, and the thermally stable TiO2 nanotubes prepared by treating hydrogen titanate nanotubes with a sol containing titanium, were used as supports, and Pt nanoparticles were deposited on the supports via the photodeposition method. The catalytic performances of as-prepared and calcined Pt/TiO2 catalysts for the hydrogenation reaction of cyclohexene were evaluated. The results showed that the effects of the support and calcination temperature on the catalytic performances of Pt/TiO2 catalysts were obvious and significant. The thermally stable nanotubular TiO2-supported Pt catalyst exhibited better catalytic performance than the other TiO2-supported Pt catalysts. In addition, it was discovered that the calcination can enhance the catalytic activity of Pt/TiO2 for hydrogenation greatly.
