This paper describes the results of optimization of the V/Sb ratio in the binary supported V-Sb oxide catalysts for oxidative dehydrogenation of isobutane and clarifies the nature of the promoting and doping effects of antimony on the catalyst behavior. Addition of the optimal amount (10 at.%) of antimony to alumina supported vanadium oxide creates on the surface of the Sb-doped catalyst new form of reactive oxygen with higher binding energy, increases rate of active phase redox transformations, decreases the amount of carboxylates on catalyst surface and thus prevents the coke formation and catalyst deactivation.
