摘要：
The ESR spectra of catalyst V2O5/gamma-Al2O3 and its activity for the dehydrogenation of isobutane were in-. vestigated. On the basis of the results of the ESR spectroscopy associated with the TPR results, it is suggested that there is a strong interaction between V2O5 and gamma-Al2O3 and the V4+ species on the surface is the active center of catalyst V2O5/gamma-Al2O3 for this reaction.
