【Abstract】 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 17 O NMR and dynamic nuclear polarization surface enhanced NMR spectroscopy. The development trend for investigating oxide nanomaterials with solid-state NMR spectroscopy is also introduced.更多还原
