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

[EN] 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 (PE...

Descripción
Sumario:[EN] 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 & Aring;3), and similar to that of the aluminogermanate PKU-9
