摘要: 本文首次报导了在0.3Na2O /0.08Zn(Ac)2 /SiO2 /0.15TPAOH /0.12柠檬酸 /100H2O的体系中水热合成含锌MFI沸石. 对合成产物用XRD, 29Si MAS NMR和EXAFS等一系列方法进行了表征. 结果表明,合成产物为含锌MFI沸石,锌原子进入到分子筛骨架.

Abstract: A suitable synthesis condition of MFI-like zincosilicalite was obtained and was first reported in this paper. The molar ratios is as follows: 0.3Na2O /0.08Zn(Ac)2 /SiO2 /0.15TPAOH /0.12 Citric acid/100H2O, the reaction was carried out at 200oC for 7~10 days. The synthesized samples were characterized with XRD, 29Si MAS NMR and EXAFS, etc. The results show that the obtained sample is MFI-like zeolite. 29Si MAS NMR and EXAFS indicate that Zn atoms have been incorporated into the framework.

Key words: zincosilicalite, MFI-like, synthesis, characterization, EXAFS
