Abstract: VO_X/MCF catalysts were prepared by two-solvents impregnation method and characterized using N₂ physics adsorption, X-ray diffraction (XRD), transmission electron microscopy(TEM), raman spectroscopy (Raman Spectroscopy), temperature-programmed desorption(TPD), temperature-programmed reduction(TPR). And also, the catalytic performances of catalysts were tested for selective oxidation of propane. Compared with the catalyst prepared by general impregnation, the catalyst prepared by two-solvents impregnation method showed better catalytic performance. It may be conduced to the better dispersion of vanadium oxide of the catalyst prepared by two-solvents impregnation method , whereas the highly dispersed vanadium state are the active positions of reaction of selective oxidation of propane.

Key words: two-solvents; VO_X/MCF; highly dispersed; propane; selective oxidation
