X射线晶体学和电子晶体学在分子筛结构表征中的应用

Abstract

Zeolites, a class of crystalline microporous materials with unique channels or cavities, have excellent performance in adsorption, separation, and catalysis. In order to correlate the structure-property relationship, it is essential to determine the crystallographic structures of zeolite at the atomic level. In this review, a series of conventional and emerging techniques regarding X-ray crystallography and electron crystallography for characterizing the crystallographic structures of zeolites through real space and reciprocal space are introduced. Furthermore, 85 recently discovered novel zeolites are systemically summarized based on the structure determination approaches and their chemical compositions. Nine zeolites with different framework type codes(FTCs) are further highlighted due to their unique synthetic methodologies or structural features. Show more
