The supports of MPO4 (M = Al, Zr, Ca) were prepared and 0.6 % similar to 6.0%V2O5 was supported on them. The catalysts are effective in the oxidative dehydrogenation of propane. The selectivity of C3H6 over the catalysts decreases in the order of V2O5/Ca-3(PO4) (2)>V2O5/Zr-3(PO4)(4)>V2O5/AlPO4, which followed the same trend of the basicity of the supports. The properties of the supports and the amount of loading had an effect on the redox property and the catalytic behavior of the catalysts. The ESR results indicated that the redox couple of V5+/V4+ responded to the activity of oxidative dehydrogenation for propane.
