Abstract  The copper doped titanium dioxide was prepared by immersion method. Photocatalytic activity was investigated with acetic acid as a model reactant, and the photocatalyst was analyzed by means of XPS. The enhanced degradation rate of acetic acid is attributed to increased charge separation and interfacial charge-transfer rate on the surface of the doped photocatalyst.
