Abstract: The mesoporous catalytic materials for oxidative dehydrogenation (ODH) of propane to propene，especially supported vanadia mesoporous catalysts，were reviewed. The mechanism of ODH and the influence of the properties of supports and preparation methods one activity and selectivity were introduced，and the way to improve catalytic performance was discussed. The influence of pore structure on ODH process was analyzed. Dispersion of catalyst active components and number of active sites could be enhanced by optimizing pore diameter and specific surface area. The stability of catalyst pore structure at a high temperature and service life should be the focus in future research.

Key words: oxidative dehydrogenation, supported vanadia mesoporous catalysts, conversion of propane, selectivity of propene
