沸石是重要的无机结晶微孔材料,在催化、离子交换和吸附/分离领域具有广泛的应用。固体核磁共振(NMR)光谱技术在分子结构和动力学行为的原子水平上具有优势,是研究沸石分子筛及其催化反应的有力工具。本文综述了近年来固体核磁共振技术在分子筛和含金属分子筛骨架结构、催化活性中心和分子间相互作用研究中的进展。沸石催化的反应,包括甲醇和乙醇转化的机理理解的进展作为选定的例子。最后对固体核磁共振技术在分子筛中的应用前景进行了展望。本文综述了固体核磁共振技术在分子筛催化剂及相关催化反应中的应用,并展望了固体核磁共振技术在分子筛领域的前景。
Zeolites are important inorganic crystalline microporous materials with a broad range of applications in the areas of catalysis, ion exchange, and adsorption/separations. Solid-state nuclear magnetic resonance (NMR) spectroscopy has proven to be a powerful tool in the study of zeolites and relevant catalytic reactions because of its advantage in providing atomic-level insights into molecular structure and dynamic behavior. In this review, we provide a brief discussion on the recent progress in exploring framework structures, catalytically active sites and intermolecular interactions in zeolites and metal-containing ones by using various solid-state NMR methods. Advances in the mechanistic understanding of zeolite-catalysed reactions including methanol and ethanol conversions are presented as selected examples. Finally, we discuss the prospect of the solid-state NMR technique for its application in zeolites. This review highlights the application of state-of-the-art solid-state NMR spectroscopy to zeolite catalysts and relevant catalytic reactions and discusses the prospect of solid-state NMR technique in the field of zeolites.
