摘要
采用水热晶化法,以甲基三乙基溴化铵为模板剂,首次合成出杂原子Sn-ZSM-12型分子筛。利用X射线粉末衍射、X射线光电子能谱,红外光谱,^(29)Si MAS NMR及电子探针等技术验证杂原子Sn存在于分子筛骨架上。对其物化性能进行了研究。
In this paper we first used methyltriethylamne bromide as template to synthesize hydrothermally heteroatom Sn-ZSM-12. type molecular sieves, and erified by means of x-ray diffraction, XPS, IR, ^(29)Si MAS NMR and EPMA that heteroatom Sn was located in the frameworl of the molecular sieves. The physicochemical properties of Sn-ZSM-12 type molecular sieves were studied.
