In this study, titanium dioxide (TiO 2 ) pure and doped prepared with tungsten at 5, 7 and 9 %, using pulse laser ablation method. The influence of different doping ratio of tungsten investigated on the structural properties and optical properties. X-ray measurement showed that the crystal size was increased by increasing doped concentration. From UV-visible data it has been found that the tungsten doping leads to a change in the optical band gap. ApplicationTiO 2 as photo catalyst was studied on the degradation of methylene blue (MB) dye under UV illumination, which revealed the highest degradation of MB at a ratio of 9%.
