Super-Hydrophilic Lu3+-Doped TiO2 Photocatalysts for Self-Cleaning Applications

摘要：

　　The self-cleaning glasses can be realized by coating the photoinduced super-hydrophilic Lu3+-doped TiO2 thin films via innovative ultrasonic-sol-gel route.The composition,structure and performance of the as-obtained material were characterized by XRD,SEM,FT-IR and UV-vis.The super-hydrophilicity is assessed by contact angle measurement.Photocatalytic properties of these films are evaluated by degradation of methyl orange under UV irradiation.The results indicate that the crystalline phase composition of Lu3+ doped TiO2 films is anatase,and the particle size is from 6 to 15 nm.In addition,Lu3+ doping can bring the red shift of the optical absorption edge of TiO2.The films exhibit excellent super-hydrophilicity and photocatalytic properties after UV radiation and the hydrophilicity can maintain for a long time in the dark place,which favors greatly the self-cleaning function of the films.
