Platinum Loading

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.

Synergic Effect

CdS/Ag2S/g-C3N4 ternary composites showed excellent photocatalytic performance toward H2 evolution. Their improved photocatalytic activity could be attributed not only to the synergic effect, but also to the introduction of Ag2S.
