Synthesis of acrolein from partial oxidation of propane on Mo–V–Te–P–O catalysts prepared by different methods

Abstract

The Mo–V–Te–P–O catalysts were prepared by different methods and used for selective oxidation of propane to acrolein. It was found that different preparation methods of the catalysts could greatly affect the elemental valence of the active component and substantially affect the catalytic activity. These catalysts were characterized by X-ray powder diffraction, H 2 − temperature programmed reduction and O 2 − derivative thermogravimetric analysis studies, which revealed that the existence of (V 0.07Mo 0. 93) 5O 14 phase in the catalysts could be very important for the selective oxidation of propane to acrolein.
