The catalytic properties of V2O5, supported in quantity of 5 wt. % on SiО2, TiО2 and titanoaerosils with the different contents TiО2, were investigated in reaction of propane oxidative dehydrogenation to propylene. The maximal propane conversion and maximal selectivity of propylene formation was shown the catalyst on titanoaerosil which the titatium ions are substituted for silicon and it do not form separate phases TiO2. By the NH3 temperature-programmed desorption it was shown that titanoaerosils contain strong oxygen-containing acid sites which energetically close to TiО2 acid sites.
