Three rare earth oxyfluorides Sm2O3/4CeF3, Nd2O3/4CeF3 and Y2O3/4CeF3 were prepared. They were active in oxidative dehydrogenation of propane and isobutane with high selectivity to propene and isobutene. The propane is easier to dehydrogenate than isobtuane, and the isobutane is easier to crack. XRD measurements indicated the existence of new phase such as CeO2 and REF3 or REOF as a result of the exchange between F- and O2- during the preparation. The insitu Raman spectra implied that O-2 was the active species.
