The catalytic reactivity of titanium dioxide supported on SBA-15 catalyst for selective oxidation of benzyl alcohol

Titania doped Mesoporous SBA-15 with various metal ratios was prepared by wet chemical route. Several phyisco chemical methods were applied to determine the structural and chemical property of the catalyst such as XRD, BET, FT-IR, TEM, SEM, and UV–Vis diffuse reflectance spectroscopy. The prepared SBA-15 catalyst has a hexagonal structure after the addition of zirconium doesn’t affect the structure of the SBA-15 catalyst it is also confirmed by TEM analysis. Titanium ions are tetrahedrally coordinated with silica framework which is confirmed by DRS-UV analysis. The catalytic performances of the Ti-SBA-15 catalysts were examined in the BzOH conversion under acetonitrile as a solvent and tert-butyl hydroperoxide (TBHP) as an oxidant. The reaction parameters like the molar ratio of H2O2: BzOH, catalyst amount, temperature, and reaction time were explored in detail. The ST-30 is the best catalyst composition of the prepared catalyst with a maximum conversion of 85% and selectivity of 98%. The recycling studies show that the synthesized Ti-SBA-15 catalyst is more stable up to five consecutive runs.
