| Abstract: | TiO_2 and TiO_2-SiO_2 thin films were prepared at low-temperature with hot water treatment.Theircrystal structure,surface morphology and transparency were characterized by XRD,AFM and UV-Vis spectrarespectively,and the effects of addition of SiO_2 in the films on their performances after treatment with hot waterwere analyzed.The evaluations of photocatalytic activities of thin films were carded out by degradation of rho-damine B in water solution under UV irradiation.The results showed that the thin films prepared at low tem-perature with hot water treatment have high reactivitity for degradation of rhodamine B and the addition of SiO_2can significantly increase the photocatalytic reactivitity. |

| Keywords: | Hot water treatment TiO_2 thin films AFM Low temperature Photocatalysis |
