The activity of Ti-pillared montmorillonite for photocatalytic oxidative desulfurization was investigated using 2,5-dimethylthiophene dissolved in n-octane as a model organosulfur compound in gasoline. Deep desulfurization of sulfur-containing compounds was achieved using Ti-pillared montmorillonite and an oil/acetonitrile two-phase extraction, with O2 as the oxygen source and photoirradiation with UV light. Using this approach, a mass of sulfur compounds were oxidized and successfully removed from the model gasoline under very mild reaction conditions. Besides N2 sorption, UV-Vis spectroscopy was used to characterize the Ti-pillared montmorillonite, which was prepared by the sol–gel method.
