摘要/Abstract

摘要： The ESR spectra of catalyst V₂O₅/γ-Al₂O₃ and its activity for the dehydrogenation of isobutane were investigated. 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 γ-Al₂O₃ and the V⁴⁺ species on the surface is the active center of catalyst V₂O₅/γ-Al₂O₃ for this reaction.
