杂原子Ti-ZSM-12分子筛的合成与结构表征

The Synthesis and Structural Characterization of Heteroatom Ti-ZSM-12 Molecular Sieves

以甲基三乙基溴化铵为模板剂,水热晶化法合成出杂原子Ti-ZSM-12型分子筛.X射线衍射,扫描电镜,IR及XPS等现代技术手段研究表明杂原子Ti取代骨架Si原子而存在于ZSM-12分子筛骨架上.

Using MTEABr (methyl-triethyleneamine bromide) as template, we have synthesized heteroatom Ti-ZSM-12 type molecular sieves by hydrothermal crystalline method. The research results of X-ray diffraction, SEM, IR and XPS show that heteroatom Ti substitute the framework silicon atom and exist in the framework of ZSM-12 molecular sieves.
