Abstract：
Solid-state NMR spectroscopy (ssNMR) can provide details about the structure, host-guest/guest-guest interactions and dynamic behavior of materials at atomic length scales. A crucial use of ssNMR is for the characterization of zeolite catalysts that are extensively employed in industrial catalytic processes. This review aims to spotlight the recent advancements in ssNMR spectroscopy and its application to zeolite chemistry. We first review the current ssNMR methods and techniques that are relevant to characterize zeolite catalysts, including advanced multinuclear and multidimensional experiments, in situ NMR techniques and hyperpolarization methods. Of these, the methodology development on half-integer quadrupolar nuclei is emphasized, which represent about two-thirds of stable NMR-active nuclei and are widely present in catalytic materials. Subsequently, we introduce the recent progress in understanding zeolite chemistry with the aid of these ssNMR methods and techniques, with a specific focus on the investigation of zeolite framework structures, zeolite crystallization mechanisms, surface active/acidic sites, host-guest/guest-guest interactions, and catalytic reaction mechanisms.
摘要：
固态NMR光谱（ssNMR）可以提供有关结构的详细信息，原子长度尺度下材料的主客体相互作用和动态行为。ssNMR的关键用途是表征广泛用于工业催化过程的沸石催化剂。本文旨在重点介绍ssNMR光谱的最新进展及其在沸石化学中的应用。我们首先回顾了当前与表征沸石催化剂相关的ssNMR方法和技术，包括先进的多核和多维实验，原位核磁共振技术和超极化方法。其中,强调了半整数四极核的方法学发展，约占稳定NMR活性核的三分之二，广泛存在于催化材料中。随后，我们介绍了在这些ssNMR方法和技术的帮助下理解沸石化学的最新进展，特别关注沸石骨架结构的研究，沸石结晶机理，表面活性/酸性位点，host-guest/guest-guest交互,和催化反应机理。
