TiO2 powder was prepared by sol-gel method using butyl titanate(C16H36O4Ti4) as the titanium source and anhydrous ethanol(C2H6O) as the organic solvent respectively,and then the obtained TiO2 was doped with copper and silver.The products were characterized by scanning electron microscopy(SEM) and X-ray diffraction(XRD).The effect of dopant dosage on the crystal form of TiO2 was analyzed.The degradation of methylene blue by the synthesized Cu/TiO2 and Ag/TiO2 photocatalysts was investigated under UV irradiation(365 nm),and the effect of dopant concentration on the photocatalytic activity of TiO2 was also analyzed.
