Catalytic properties of V−Mo−O systems have been studied in acrolein oxidation. When catalysts are activated in reaction mixtures at 673 K, then a solid solution of molybdenum oxides in reduced vanadium oxides is formed, which is responsible for deep oxidation. Also, several compounds are produced, which by their activity and selectivity to acrylic acid formation are arranged in the sequences VMo3O11≅VMo2O8+x>V6Mo4O25, and VMo3O11>VMo2O8+x≫V6Mo4O25, respectively.
