Selected Pt/WO3-ZrO2 catalysts, promoted by Al, Si and Fe metal ions and isomorphously substituted into the zirconia framework, were studied and compared with their undoped equivalents as catalysts for C7 isomerization. They were characterized by XRD, UV–vis and TPD-TPR techniques. A mechanism was proposed for the positive dopant effect on the catalyst activity.
