Benzaldehyde is an important chemical and has tremendous application in cosmetics, perfumery, food, dyestuff, agrochemical and pharmaceutical industries. In the present investigation, threefold increase in oxidative property of mesoporous Ti-SBA-15 was observed by treatment with chlorosulfonic acid. Physio-chemical properties of this catalyst were analyzed by BET surface area, X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), FTIR, and NH3-temperature programmed desorption (TPD) techniques. The super acidic nature of the catalyst is shown by NH3-TPD profile. Enhanced acidity of the catalyst increases benzyl alcohol conversion from 20 to 62% without affecting benzaldehyde selectivity (95%).
