The organic sulfur compounds in transportation fuel were converted to SO x during the combustion，which not only caused serious pollution of environment，but also harmed human health.So，the ultra-deep desulfurization technology of fuel oil under moderate condition has become the focus of many scientific researchers.The hollow drum-shaped titanium-containing silica with hierarchically mesoporous structure was successfully synthesized by using a polyelectrolyte-surfactant mesomorphous complex templating method.Through characterization，including small-angle X-ray diffraction（XRD），electron scanning electron microscopy（SEM），electron transmission electron microscopy（TEM），nitrogen adsorption-desorption and ultraviolet-visible spectroscopy，the obtained hierarchically porous titanium-containing silica material possessed ordered cubic Pm-3n mesomorphous phase，hierarchically mesoporous architecture，and high framework titanium content.Owing to the secondary mesoporous structure and plentiful titanium active sites in the framework，the porous silica exhibited superior catalytic oxidative desulfurization performance and cycling stability at room temperature.In addition，the titanium-containing silica possessed strong adsorptive effect toward the oxidative product with strong polarity，which achieved oxidative-adsorptive process for one-pot desulfurization.
