合成了SiO_2-Al_2O_3-NaOH-TMA-H_2O体系的Fu-9型分子筛和SiO_2-Al_2O_3-H_3BO_3-NaOH-TMA-H_2O体系的Bi-Si-Al的Fu-9型分子筛,并且得到了后者的三元晶化区域图。用X射线衍射图和固态高分辨~(11)B核磁共振谱研究了这些分子筛的结构,表明硼原子处在沸石正四面体位置上。用程序升温脱附方法研究了它们的表面酸性质。
Fu-9 molecular sieve of SiO_2-Al_2O_3-NaOH-TMA-H_2O system and Bi-Si-Al Fu-9 zeolite of SiO_2-Al_2O_3-H_3BO_3-NaOH-TMA-H_2O system were synthesized and the Ternary crystallization area diagram. The structure of these molecular sieves was investigated by X-ray diffraction and solid-state high resolution ~ (11) B nuclear magnetic resonance spectroscopy, showing that the boron atoms are located at the normal tetrahedron of the zeolite. Their surface acidity was studied by temperature programmed desorption.
