Abstract: The application of solid-state NMR spectroscopy spans multidisciplinary areas of physics, chemistry and materials science. Solid-state NMR has been fully integrated into catalysis science and played a critical role in the study of heterogeneous catalysis by providing a powerful tool to tackle important problems. The increasing of the complexity of heterogeneous catalytic systems brings about new challenges on the one hand, and also opens up new opportunities on the other hand for solid-state NMR. In this article, the recent progress of solid-state NMR development and its application in heterogeneous catalysis is briefly reviewed. The obstacles for the development of solid-state NMR are discussed and the status of the research of solid-state NMR in heterogeneous catalysis in China is introduced. Based on the comparison with the world-class level, the technologies which are in the "cut-throat competition" position are summarized. Finally, the major opportunities and future research directions for solid-state NMR are highlighted.
