Enhanced photoinduced super-hydrophilicity in sol-gel TiO2 thin films with co-doped Sn/Nb. Kaleji, B. K. & Hosseinabadi, N. Journal of Sol-Gel Science and Technology, 69(2):412–417, February, 2014. WOS:000330975000023

In this work, Sn and Nb co-doped TiO2 were coated on glazed porcelain substrates via sol-gel dip coating method. Field emission-scanning electron microscopy, transmission electron microscopy, and UV-vis spectrophotometer were used to evaluate thickness and optical properties of the thin films. Surface chemical state of thin films was examined by atomic X-ray photoelectron spectroscopy. Water contact angle on the film surfaces was measured by a contact angle analyzer under solar light irradiation. The optical results indicated that Sn/Nb dopant in TiO2 thin film changed the absorption edge from ultraviolet to visible light and exhibited excellent photo-catalytic ability for degradation of methylene blue solution under solar irradiation. Wettability results indicated that Sn and Nb dopant ions had significant effect on the hydrophilicity property of thin films.
