Abstract
Properties of the ZSM-5 zeolite modified with VO2+ ions in a one-step exchange reaction in water medium have been investigated. Physicochemi cal characterization (chemical analysis, XRD, MAS n.m.r., e.s.r.) show s that during the preparation the ZSM-5 zeolite structure remains pres erved and the vanadyl ions enter the zeolite structure. Sample acidity is of Bronsted and Lewis types and can be reduced by treatment with N aCl solution. Doping with vanadyl ions produces catalysts active in am moxidation of m-xylene.
