Abstract
A series of bulk vanadium mixed oxides (Ce, Al, Fe or Cr) were successfully prepared. Methanol and propane were proposed as probe molecules to investigate the redox properties of this series of bulk vanadium mixed oxides and a qualitative picture of the redox properties was obtained. Specifically, we tested steady-state methanol oxidation at range 250–300 °C and oxidative dehydrogenation (ODH) of propane to propene at range 350–550 °C. We also explored the turn over frequency of redox products (TOFredox) and found that the TOFredox values in methanol oxidation and ODH of propane changed in the order as CeVO4 > AlVO4 > V2O5 > FeVO4 > CrVO4.
