A systematic study of the catalytic behaviour of a FeVO4sample in the anaerobic ethanol transformation was performed and compared with reference oxides V2O5and Fe2O3. It was found that the alcohol is able to reduce the samples at 300°C. The FeVO4and V2O5samples have almost identical catalytic behaviour even if they form completely different structures during reduction. It was concluded that in the first case, Fe plays a role as a "stabilizer" of the reduced phase thanks to the formation of a spinel phase where the V is mainly present as V3+whereas in the case of V2O5the reduction under the same conditions leads mainly to a VO2phase and the presence of this V4+vanadium species catalyse side reactions.

Abstract

A systematic study of the catalytic behaviour of a FeVO4sample in the anaerobic ethanol transformation was performed and compared with reference oxides V2O5and Fe2O3. It was found that the alcohol is able to reduce the samples at 300°C. The FeVO4and V2O5samples have almost identical catalytic behaviour even if they form completely different structures during reduction. It was concluded that in the first case, Fe plays a role as a "stabilizer" of the reduced phase thanks to the formation of a spinel phase where the V is mainly present as V3+whereas in the case of V2O5the reduction under the same conditions leads mainly to a VO2phase and the presence of this V4+vanadium species catalyse side reactions.
