Effect of different dopant in the Mo-V-Te-O catalyst on the performance of selective oxidation propane to acrolein

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 H-2-TPR. The XRD characteristic of the Mo-V-Te-P-O showed that the addition of P could aggrandize the (V0.07Mo0.93)(5)O-14 phase. H-2-TPR illuminated that the MoV0.3Te0.23P0.15On catalyst took on the best redox ability.
