On the Rotational Intergrowth of Hierarchical FAU/EMT Zeolites

摘要

A structural study of a hierarchical zeolite X, which is similar to the one first synthesized by Inayat et al.was performed using transmission electron microscopy imaging and diffraction. Evidence is provided, by comparison to simulations, that this material is an intergrowth of FAU and EMTand a conceptual model is presented for the growth of the FAU material with a small fraction of EMTin an atypical morphology of assembled sheets with well-defined intersection angles.
