Abstract

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
