Synthesis and physicochemical properties of vanadium-doped zirconia-pillared montmorillonites in relation to oxidative dehydrogenation of propane

V-doped zirconia-pillared montmorillonites have been obtained by different methods and characterised with XRD, ESR, nitrogen adsorption and chemical a nalyses. The samples are microporous, their structure, texture and location of V species depending on the method of preparation. Catalytic results in the reaction of the oxidative dehydrogenation of propane to propene are dis cussed in terms of the physicochemical properties of the materials.
