Solid-State NMR Studies on the Surface Structure and Properties of Oxide Nanomaterials

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 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.
