TiO2 thin films (anatase and rutile) were prepared on soda-lime glass substrates by sol-gel method. The effects of adsorbed oxygen on the photocatalytic activity of different TiO2 crystals were studied by photocurent measurement and XPS technology. The photocatalytic activity of the different TiO2 crystals (anatase and rutile) was evaluated by the degradation of cyclohexane. The results showed that anatase was more active than rutile, which was attributed to the higher capability of adsorbing oxygen and lower electron-hole recombination rates of the anatase.
