Performance of Mo-V-Te-P catalysts supported on the SiC for propane selective oxidation to acrolein
摘要:
A series of MoTe0.15V0.1PxOn catalysts supported on the SiC were prepared by incipient wetness impregnation. The addition of P to MoTe0.15V0.1On/SiC catalysts improved the catalytic performance of selective oxidation from propane to acrolein (ACR), and the catalyst showed highest selectivity (33.7%) and yield (10.7%) when x=0.05. The MoTe0.15V0.1PxOn/SiC catalysts have been characterized by XRD, H2-TPR, Raman, XPS and NH3-TPD. The results indicated that a little H3PMo12O40 heteropoly acid and (VO)2P2O7 formed and MoO3 phase lessened after addition of P. The addition of P promoted the active species dispersed, increased the acidity on the surface, as well as might make the redox process easier. These significant differences improved the activity and selectivity of ACR.
