Abstract
A novel Zr,Ce-TiO2/SiO2 nanocomposite thin film was successfully prepared with various amounts of Zr^4+ and Ce^4+ as codopant ions for self-cleaning applications. Athin film was coated on a tile substrate by dip-coating and porous Zr,Ce-TiO2/SiO2 was obtained after heat treatment for 2 hours at 500 °C. The SEM images and XRD patternshowed that the optimum amount of doping ions in relation to Ti^3+ is 0.1%. In thiscircumstance, the most monotony of film was seen and the main formed phase was anatase. The sample structures were characterized by infrared spectroscopy. The nanocomposite films were found to be active for photocatalytic decomposition of methyl orange as an organic pollutant.
