Effect of Different Dopant in the Mo-V-Te-O Catalyst on the Performance of Selective Oxidation Propa

Several Mo-V-Te-O mixed metal oxides catalysts with different dopant were prepared and used for catalytic oxidation propane to acrolein.It was revealed that the addition of P could greatly improve the performance of the Mo-V-Te-O catalyst.The catalysts were examined by XRD and H2-TPR.The XRD characteristic of the Mo-V-Te-P-O showed that the addition of P could aggrandize the (V0.07Mo0.93)5O14 phase.H2-TPR illuminated that the MoV0.3Te0.23P0.15On catalyst took on the best redox ability.
