V2O5 and MoO3 mixed oxides supported by SiO2 were studied as the catalysts in the aqueous phase allylic oxidation of cyclohexene to unsaturated alcohol 2-cyclohexene-1-ol and unsaturated ketone 2-cyclohexene-1-one. The additional layer of TiO2 deposited by atomic layer deposition significantly suppresses the epoxidation pathway and the formation of cyclohexane oxide and cyclohexane-1, 2-diol. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM) were used to study the relationship between the structure of the catalysts and their catalytic performance. The effects on the catalytic activity of different solvent, hydrogen peroxide to cyclohexene ratio, and reusability were investigated.
