摘要
氧化物纳米材料的多种应用与其表面结构和性质密切相关.近年来,固体核磁共振波谱在相关研究中提供了关键信息.本综述总结了近期发展的、以固体核磁共振波谱为主的两种表征氧化物纳米材料表面结构和性质的方法,包括表面选择的同位素标记17O核磁共振波谱与动态核极化表面增强核磁共振波谱,并对氧化物纳米材料的固体核磁共振波谱研究的发展趋势进行了展望.
Many applications of oxide nanomaterials depend on their surface structure and properties.Solid-state nuclear magnetic resonance(NMR)spectroscopy has been used to obtain such key information in related studies.This paper summarizes two recently developed approaches based on solid-state NMR spectroscopy for determining the surface structure and properties of oxide nanomaterials,including surface-selective isotopic labeling 17O NMR and dynamic nuclear polarization surface enhanced NMR spectroscopy.The development trend for investigating oxide nanomaterials with solid-state NMR spectroscopy is also introduced.
