摘要

采用光化学诱导[2 + 2]环加成法制备了有机结构导向剂（OSDA），得到了一种纯开框架锗酸盐材料。这种名为ITQ-35的新材料的结构是通过结合进动电子衍射层析成像（PEDT）和粉末x射线衍射（PXRD）方法确定的。该材料呈现出由12环通道连接的三向8环孔，具有迄今为止报道的纯锗沸石材料中最低的骨架密度之一（12.7 T/1000 Å3），与铝锗酸盐PKU-9相似。

Open Framework Structure of the New Pure-Germania Zeolite ITQ-35 Solved by 3D Electron Diffraction

A pure open-framework germanate material is obtained using an organic structure directing agent (OSDA) prepared by a photochemically induced[2 + 2] cycloaddition reaction. The structure of this new material, named ITQ-35, is determined by combining precession electron diffraction tomography (PEDT) and powder X-ray diffraction (PXRD) methods. This material presents tridirectional 8-ring pores connected by 12-ring channels, with one of the lowest framework densities reported until now for a pure germania zeolitic material (12.7 T/1000 Å³), and similar to that of the aluminogermanate PKU-9
