Abstract: The structure and catalytic properties of BiCeVMoO catalysts with different composition for selective oxidation of propane have been investigated. It has been shown that bismuth may be substituted by a low amount of cerium while the Scheelite structure of BiVMoO remains unchanging. With the increasing of Ce (Ce/(Ce+Bi)>0.15), new phases of CeVO4 and Ce2(MoO4)3 formed. The cerium which probably entered into the lattice of BiVMoO promotes the forming of acrolein, and the selectivity to acrolein increased to a maximum at Ce/(Ce+Bi) atomic ratio=0.15 (45mol% at ∼30mol% propane conversion). Further increasing Ce content results in further oxidation of propylene and acrolein to CO x due to the strong oxidative ability of catalysts. The proper amount of introduced cerium, which probably occupied the lattice sites of Bi3+ enhanced the oxidative ability of catalysts moderately by increasing the activity and the amount of surface active oxygen species.
