Progresses of hyperpolarized 129 Xe NMR application in porous materials and catalysis

129 Xe NMR has been proven to be a powerful tool to investigate the structure of porous materials. Xenon is a monatomic noble gas which could be used as a probe due to the extremely sensitive to its local environment. Optical pumping techniques for production of hyperpolarized (HP) xenon have led to an increase of sensitivity up to orders of magnitude compared with traditional 129 Xe NMR. This review summarizes the application of this technique in porous materials and heterogeneous catalysis in recent ten years, involving of zeolites, metal-organic frameworks (MOFs), catalytic process and kinetics.
