Application of nano-structures of titanium dioxide (TiO2) films on photocatalytic activities of organic dyes was investigated. Methylene blue (MB) and cation yellow X-Gl 200% were used as organic dyes to observe decolorization. The TiO2 films were prepared on glass substrate by reactive DC magnetron sputtering. The films had thickness, grain size and root mean square surface roughness of 300 nm,  40 nm and  4 nm, respectively. Coated-TiO2 on glass and uncoated TiO2 (glass) were immerged in MB and cation yellow dyes solution. A weak ultraviolet (UV) A at peak wavelength  365 nm and intensity of 0.19 mW/cm2 was irradiated. Absorbance spectra of dyes at different UV irradiation time were observed. The efficiency of decolorization increased as UV irradiation time increased. At UV irradiation time 120 hours, coated-TiO2 showed higher percentage decolorization of MB than uncoated-TiO2 about 64%. While, at UV irradiation time 48 hours, coated-TiO2 showed higher percentage decolorization of cation yellow than uncoated-TiO2 about 84%. Under photocatalysis process of TiO2 films, at the end, MB (about 120 hours) and cation yellow dyes (about 48 hours) change to be colorless.
