Mesoporous Sulfur-Doped TiO₂ Microspheres for Catalytic Degradation of Methylene Blue under Visible Light

Article Preview

Abstract:

Mesoporous S-doped TiO₂ microspheres were synthesized via hydrothermal method using Ti (SO₄)₂ precursor and urea as homogeneous precipitate agent. The TiO₂-based catalyst samples were characterized by means of Field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), N₂ adsorption/desorption and UV-vis diffuse reflectance spectra (UV-vis DRS). Photo-catalytic experiments were carried out by catalytic degradation of methylene blue aqueous solution under visible light. It was found that the S-doped TiO₂ microspheres gave better photo-catalytic performances. The higher absorbance in the visible region explained this phenomenon. There was an appropriate Ti (SO₄)₂ amount for the catalyst with better photo-catalytic degradation.
