The oxidative dehydrogenation of propane(ODPH)to propylene is an important way to produce high value-added olefins by utilizing cheap lower alkanes.For such a reaction system,supported vanadium-based catalysts are one of the currently accepted catalysts with a good activity for the oxidative dehydrogenation of propane.To provide a reference for improving the catalytic performance of supported vanadium-based catalysts in the view of catalyst design,this paper mainly focused on some relevant researchs on vanadium-based catalysts,meanwhile,it reviewed ODPH reaction mechanism,and the effect of three different types of metal additives as well as the structure,morphology and surface acidity of the supports on the catalytic activity and selectivity of propylene during the reaction process of ODPH.
