| 英文摘要: |
| The FeVO4 catalyst was prepared by solid state salt grinding method. Electrical conductivity of FeVO4 catalyst was measured under different sequential gaseous atmospheres and at different temperatures to determine its conductivity type. The FeVO4 catalyst was characterized by x-ray diffraction (XRD), BET and H2-TPR. Its catalytic behavior for the oxidative dehydrogenation (ODH) of propane to propene was also investigated. The results show that FeVO4 catalyst is n-type semiconductor and has a good catalytic performance for ODH of propane. 34.4% conversion of C3H8 and 36.1% selectivity of C3H6 were obtained over the catalyst under 873 K. |
