| 摘 要： | 沸石作为一类最重要的固体氧化物材料，是17O固体核磁共振最早研究对象之一. 近年来，随着核磁共振谱仪磁体场强的不断提高，以及新脉冲序列的发展，17O固体核磁共振被越来越多地应用于沸石的结构表征，在研究骨架氧结构以及测定Brønsted酸位的O-H键长等方面都提供了非常丰富的信息. 本文将介绍17O固体核磁共振的特点，回顾20年来它在沸石研究方面的发展并着重介绍近期这一方面的研究突破.

| Abstract: | Oxygen atoms are major constituents of zeolites, whose arrangements in the framework play very important roles in determining the adsorptive and catalytic properties of the catalysts. In the past years, 17O solid-state NMR spectroscopy has become a powerful tool to study the short range order of the oxygen atoms in the framework of the zeolites. The studies using this technique have resulted in many insights into how the local structures of oxygen atoms are related to the properties of the catalysts. This review introduces significant advances in the 17O NMR studies of the zeolites during the last 20 years. A brief introduction to 17O solid-state NMR spectroscopy is also included. |
