Photocatalysis and Hydrophilicity of Y3+ Doped TiO2 Thin Films

Abstract:

Article Preview

Y3+ doped TiO2 coatings were successfully prepared on glass slide substrates. The phase structure, optical properties,microstructure and surface properties of the coatings were characterized by using XRD, FT-IR, UV-vis and SEM. The photoinduced super-hydrophilicity and photocatalytic activity of the films were evaluated by the water contact angle measurement and photocatalytic oxidation of Rhodamine B in air, respectively. The results indicated that the doping of Y3+ into TiO2 could improve the hydrophilicity and photocatalytic activity, and TiO2 thin films doped with Y3+ at 2-4 at.% and heat-treated at 450 oC were of super-hydrophilicity. The optimal Y3+ content for the photocatalytic activity was 4 at.% and larger film thickness was helpful to reduce the contact angle of the composite films.
