Liquid phase selective oxidation of alcohols over VPO catalysts supported on Mesoporous hexagonal molecular sieves (HMS)

Selective catalytic oxidation of alcohols to carbonyls is one of the most important chemical transformations in industrial chemistry.Numerous methods are available for alcohol oxidation, however, the common methods of alcohol oxidation use toxic, corrosive and expensive oxidants such as chromium (VI), stringent conditions like high pressure or temperatures and use of strong mineral acids [1-4].The search for new oxidation catalysts is one of the most important topics connected with both industrial and academic research. Vanadium phosphorus oxide (VPO) catalysts are effective for the oxidation of n-butane to maleic anhydride [5-8]. Potentially,supported VPO catalysts have advantages over the unsupported ones, including better heat transfer character, larger surface area to volume ratio of active component, better mechanical strength, and controllable catalyst textures. Such materials as SiO2, TiO2, Al2O3,have been used in attempts to support VPO [9].
