分子筛由于具有独特的孔道及可调控酸碱性等特征,被作为离子交换剂、吸附剂及催化剂而广泛应用于石油化工的各种催化过程中。固体核磁共振是研究分子筛结构、酸性及主客体相互作用的强有力谱学手段之一。简单概述了固体核磁共振研究分子筛的最近进展。
Zeolites are widely used as ion exchangers, adsorbents and catalysts in the chemical and petro-chemical industries because of their pore structure and acidity. Solid state NMR is a powerful tool for the characterization of the topological structure, active sites (acid sites) and host-guest interac-tion in zeolites. Recent advances in the solid state NMR characterization of zeolites are briefly re-viewed.
