Abstract: Well-organized Ti- and V-containing silicate mesoporous mesophase materials (MMM) were synthesized using C16H33N(CH3)3Br and characterized by elemental analysis, IR, DRS-UV, XRD, and N2 adsorption. Catalytic properties of these materials in alkene and thioether oxidations with aqueous H2O2 were examined. The structure–activity study was performed for the C16-(Ti,Si)-MMM catalysts with the Si/Ti atomic ratio ranged from 19 to 166. The samples with the Si/Ti atomic ratio in the range of 49–124 showed the highest catalytic activities. Both structure perfection of the silicate matrix and degree of isolation of titanium ions in it appeared to be crucial factors determining catalytic activity of C16-(Ti,Si)-MMM in alkene oxidation. For efficient oxidation of more nucleophilic substrates (thioethers) the structural perfection of the C16-(Ti,Si)-MMM catalysts was less important. No titanium leaching occurred even in 1.1 M H2O2 solution at 353 K, whereas vanadium leaching was already pronounced at [H2O2]=0.05 M and room temperature. The oxidation processes proved to be true heterogeneous for C16-(Ti,Si)-MMM and mostly homogeneous for C16-(V,Si)-MMM.
