摘要：

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