摘要： 在含氟的弱酸性介质中,以四丙基溴化铵为模板剂,以NH4VO3和VO2+为钒源合成出V-ZSM-5分子筛,运用XRD、SEM、IR、XPS、ESR等手段对其结构进行了表征,结果表明,钒进入了分子筛骨架,并且主要以正四价态存在。

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.
