Solid-state NMR spectroscopy is a well-established method to obtain atomic-level information about the structure of inorganic materials, but its use is often limited by low sensitivity. We review how solvent generated dynamic nuclear polarization can be used to increase sensitivity in solid-state NMR of inorganic materials, with emphasis on our recent method for hyperpolarization of proton-free bulk. We use selected examples to show how overall gains in sensitivity can be observed in both the surface and bulk spectra of inorganic compounds such as lithium titanate. The hyperpolarization methods reviewed here can be used to improve NMR sensitivity for a range of inorganic materials.
固态核磁共振光谱法是一种成熟的获取无机材料结构原子级信息的方法，但其应用常常受到低灵敏度的限制。我们回顾了溶剂产生的动态核极化如何用于提高无机材料固态核磁共振的灵敏度，重点介绍了我们最近的无质子体超极化方法。我们通过选定的例子展示了如何在钛酸锂等无机化合物的表面和体光谱中观察到灵敏度的整体提高。本文所回顾的超极化方法可用于提高一系列无机材料的核磁共振灵敏度。
