Quantitative determination of oxygen defects, surface lewis acidity, and catalytic properties of mesoporous MoO3/SBA-15 catalysts

Adsorption and oxidation of 4,6-DMDBT molecule were taken place on the surface of α-MoO3 clusters in MoO3/SBA-15 catalysts within the mesoporous channel. When the formed sulfone was extracted by acetonitrile, the active sites were immediately regenerated for further reaction.251
