Paper Title:
Study of Cyclohexane Photooxidation over Pt-WO3 Catalysts Mixed with TiO2 under Visible Light Irradiation
  Abstract

The photooxidation of cyclohexane to cyclohexanone, cyclohexanol and CO2 was carried out by visible light irradiation to tungsten oxide photocatalysts. The physical mixing of tungsten oxide and titanium oxide (WO3+TiO2) led to the high photocatalytic activity. It was speculated that the physical mixing of WO3 and TiO2 took place the charge transfer between WO3 and TiO2, and this inhibited the recombination between electrons and holes on the WO3 surface. The platinum loading on WO3 further developed the photocatalytic activity of WO3+TiO2 photocatalyst. Hence, the degree of the recombination between electrons and holes may dominate the photocatalytic activity of cyclohexane oxidation.
