We report here the investigation of the individual V2O5, binary V2O5-SnO2, V2O5-TiO2, and ternary V2O5-TiO2-SnO2 catalysts in oxidation of 4-methylpyridine (4-MP) to isonicotinic acid (INA). The experimental results were interpreted by the quantum chemical computation (Gaussian 09 W). We studied the influence of oxide-modifiers on the nucleophilic properties of vanadyl oxygen and also on the deprotonation enthalpy of methyl group of chemisorbed substrate.
