摘要:

分子筛是一类具有规则孔道或笼结构的晶态微孔材料, 在吸附、 分离和催化中都表现出了优异的性能. 为了探索其结构与性质的关系, 在原子尺度上研究分子筛的微观结构是十分必要的. 本综述介绍了一系列与X射线晶体学和电子晶体学相关的表征技术(倒易空间和正空间)在分子筛结构表征中的应用. 随后, 基于分子筛的结构表征方法和化学组成, 对2007年之后发现的85种新分子筛进行了系统总结, 对其中9种具有独特合成方法或结构特征的分子筛进行了详细介绍.

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.

Key words: Zeolite, Structural characterization, X-ray crystallography, Electron crystallography, Framework type code
