Abstract: The V-ZSM-5 type molecular sieve was synthesized in a weak acid medium in the presence of F- ions, and with tetrapropylammonium as a template agent, NH4VO3 and VO2+species as vanadium sources.Investigation on the structure was performed by means of XRD, SEM,IR,XPS and ESR.The results indicated that the majority of vanadium was V4+ species, which was introduced into the framework of zeolites.
