Synthesis and characterization of VPO catalysts with the different ratio of PV in organic medium for partial oxidation of n-butane to maleic anhydride

In this paper, vanadium phosphorus oxide (VPO) catalysts were synthesized with the different P/V ratio (0.5, 1.0, and 2.0) in organic medium. The structure of catalysts were characterized by XRD, SEM, AA, and BET instruments. The activity and selectivity of those synthesized VPO catalysts were investigated with partial oxidation of n-butane to maleic anhydride.
