Vanadium-molybdenum oxides supported on Al2O3, CeO2 and TiO2 were prepared by a "wet" impregnation method, characterized using XRD, N2 adsorption, UV-Vis spectroscopy, electrical conductivity measurements and tested in the oxidative dehydrogenation of isobutane. The catalytic perfor- mance in the oxidative dehydrogenation of isobutane at 400-550 °C depended on the nature of support and on the content of VMoO species on the support. The catalysts supported on alumina were more active and selective than those supported on ceria and titania.
