Titanium dioxide (TiO2) is a promising material because it has very special properties such as large band gap, good photoactivity, nontoxicity, high chemical stability, and so on. Therefore, TiO2 is utilized in many areas including photocatalysts, gas sensors, photovoltaic cells.In this study, we fabricated the TiO2 inverse opal (TIO) films through dip coating process via modified sol-gel method. The inverse opal structure has large surface area and it makes to improve the phtocatalytic performance of TiO2. After that, a small amount of noble metal was coated on the surface of TIO films through photodeposition method to inhibit charge carrier recombination and enhance the photoactivity. This noble metal-deposited TIO films can be used as a developed photocatalyst.The resultant samples were characterized by FE-SEM, XPS and UV-Vis spectroscopy. Furthermore, photocatalytic activity was analyzed by decomposition of MB.
