摘要
介绍了固体核磁共振波谱法(NMR)中的魔角旋转(MAS)、多量子跃迁(MQ MAS)、多核共振(REDOR等)、原位测试(in situ)和核磁共振成像(MRI)等技术在考察催化材料中Al等四极矩不为零的核、表征骨架内外Al的配位和结构及研究反应物分子在催化剂上的吸附状态和催化机理方面的应用进展。评述了固体NMR在炼油和化工催化材料研究中的应用实例。
Numerous new developments and applications of solid-state NMR technique have evolved. The most important progress is the high-resolution techniques for quadrupolar nuclei, double-resonance methods and multiple-quantum techniques for the study of interatomic distance between the atoms in the framework and the atoms in the adsorbed molecule. The instrument improvement such as MAS and DOR, pulse sequences development for multi quantum resonance （MQMAS）, double resonance like REDOR, specially designed in situ process, and magnetic resonance imaging （MRI） are introduced in this paper through the examples of the characterization of catalytic materials used in the refining and petrochemical industries.
