英文摘要: Large spin polarization can be produced in Xe-129 nuclei by laser optical pumping and spin exchange. Hyperpolarized Xe nuclear magnetic resonance (NMR) can increase the measurement sensitivity by several orders of magnitude compared to the thermally polarized Xe NMR. It is a powerful tool for studying the pore structure of a material and the particle distribution inside the pores. This paper introduced the basic principles of hyperpolarized Xe-129 NMR and reviewed its applications in the characterization of porous catalytic materials, especially with respect to the inorganic microporous and mesoporous materials. The prospect of this technique was also discussed.
