Notes:
Nano anatase TiO2 thin films on glass slide substrates were prepared via a dip-coating methodusing refluxed sols (RS) as precursors, then dried under infrared light and calcined at 500°C for 30min.The RS sols and TiO2 films were characterized by FT-IR, XRD, TEM, UV-Vis and SEM. Thephotocatalytic activities of the film samples were tested by the degradation of methyl orange solution witha concentration of 10mg/L under UV light irradiation. The results reveal that the RS sols are flavescent,alkalescent and contain needle-like anatase crystals. The TiO2 films are uniform, compact and transparent,their maximal light transmittance exceed 80% under visible light region. The degradation of methylorange results illustrate that the RS-6 TiO2 thin films show the best photocatalytic activities, thedecoloration rate of the methyl orange solution with RS-6 TiO2 thin films reachs 99% after irradiated160min under UV light
