Nano-sized S₄^2-/TiO₂ particles were prepared from TiCl₄ and (NH₄)₂SO₄ by the Sol-Gel method and characterized by XRD and FTIR.Photocatalytic degradation of methylene blue solution under ultraviolet radiation was carried out by using nanoparticle TiO₂ doped with S₄^2- as the photocatalyst.It was found that doping of S₄^2- into TiO₂ by the Sol-Gel method remarkably improved its structure.The reaction of photo-catalysis for methylene blue is in conformity with the first order kinetic law in appearance within the concentration range between 6 mg/L and 15 mg/L.The appearance rate constant of the reaction decreases and the half-life period of the reaction increases with increasing of initial concentration of methylene blue in water, respectively.
