| Abstract: | The anatase TiO2 nano-power was prepared by the sol-gol method. The size,appearance,structure and property of TiO2 were analyzed by XRD,SEM,FTIR and AFM. The photocatalytic oxidation properties were examined by the degradation of methly red. The results show that the samples are anatase TiO2 particles with diameter of 20 nm. When the concentration of methyl red is 20 mg/L and the dosage of the powers is 0.7 g/L ,the degradation rate of methyl red is up to 95.58% after irradiated half an hour with the 8 W ultraviolet lamp with L=365 nm. |
