Abstract: Photocatalysts of TiO2 supported on activated carbon was prepared by a vacuum absorption-hydrolysis method.The photocatalytic activity was investigated with 1,3-dichlorobenzene as a probe molecule.The results indicate that the supported TiO2 catalyst was affected by the heating temperature.And recycled times had a little effect on its photocatalytic activity.

Key words: TiO2, activated carbon, photocatalysis, 1,3-dichlorobenzene
