The applicability of molybdenum-containing catalysts based on SBA-15, which were synthesized in one stage by a co-condensation method, to the oxidation processes of various organosulfur compounds was demonstrated for the first time. The composition and structure of the obtained materials were confirmed using a set of modern physicochemical methods, such as low-temperature nitrogen adsorption/desorption, X-ray spectral fluorescence analysis, X-ray diffraction (XRD) analysis, TEM, and IR spectroscopy. The effects of the amount of the active phase and the process conditions on the oxidation of a model mixture of dibenzothiophenes were studied. It was shown that the resulting catalyst worked at least in four cycles without significant loss of activity. A sample containing 5 wt % molybdenum made it possible to achieve a dibenzothiophene conversion of 100% in 5 min under the following conditions: 0.5 wt % of a 5% Mo-SBA-15 catalyst, the molar ratio H2O2 : S = 6 : 1, and T = 80°C.
