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%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
