Alumina-supported vanadium oxide catalysts (V2O5∼ 10wt.%) with and without SnO2were tested in the dehydrogenation of isobutane at 590°C under atmospheric pressure and were characterized by BET, XPS, TPR, XRD and RAMAN. It is found that the electron interaction exists between V and Sn oxide species on the surface of support. The doping of appropriate amount of SnO2leads to that the surface vanadia of catalysts is more reduced and is more highly dispersed than undoped catalyst. V2O5/γ-Al2O3catalyst with 3wt.% of SnO2, exhibited higher reactivity in dehydrogenation of isobutane to isobutene.
