上海科技大学马延航团队报道了三维电子衍射在沸石结构测定中的应用。相关研究成果发表在2024年1月24日出版的《结构化学》。

沸石因其在催化、吸附/分离、离子交换等领域的广泛应用而受到广泛关注。确定沸石的原子晶体结构对于理解其功能和探索其应用至关重要。由于合成大单晶的困难，许多沸石的结构无法用传统的单晶X射线衍射方法解决。三维电子衍射（3D ED）在过去十年中得到了快速发展，并在沸石的结构测定中显示出强大的能力。

该篇综述中，研究人员简要介绍了3D ED的发展历史，总结3D ED在沸石结构分析中的应用进展，以及该研究领域的几个典型例子。

Abstract: Zeolites have received great attention due to their wide applications in various fields such as catalysis, adsorption/separation, ion exchange, etc. Determining the atomic crystal structure of zeolites is crucial to understanding their functions and exploring their applications. Due to the difficulty of synthesizing large single crystals, the structures of many zeolites cannot be solved using conventional single-crystal X-ray diffraction methods. Three-dimensional electron diffraction (3D ED) has witnessed rapid development during the past decade and has shown its powerful ability in the structure determination of zeolites. In this review, we will briefly introduce the development history of 3D ED and summarize recent advances in the application of 3D ED for the analysis of zeolite structures, along with several typical examples in this research field.
