Study the photo catalytic activity of titanium dioxide nanoparticles and the impact on the degradation of methylene blue

Abstract

In this study, titanium dioxide (TiO2) 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. ApplicationTiO2 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%.
