Efficient and reusable ordered mesoporous WO _x /SnO₂ catalyst for oxidative desulfurization of dibenzothiophene.

ABSTRACT: The oxidative desulfurization (ODS) of organic sulfur compounds over tungsten oxide supported on highly ordered mesoporous SnO₂ (WO _x /meso-SnO₂) was investigated. A series of WO _x /meso-SnO₂ with WO _x contents from 10 wt% to 30 wt%, were prepared by conventional wet impregnation. The physico-chemical properties of the WO _x /meso-SnO₂ catalysts were characterized by X-ray diffraction (XRD), N₂ adsorption-desorption isotherms, electron microscopy, Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, and the temperature-programmed reduction of hydrogen (H₂-TPR). The characterization results indicated that these catalysts possessed mesoporou
