Development of In Situ MAS NMR and Its Applications in Material Synthesis and Heterogeneous Catalysis

ABSTRACT High-resolution magic angle spinning (MAS) NMR can afford both qualitative and quantitative information of the solid, liquid and gas phase at atomic level, and such information obtained at in situ/operando conditions is of vital importance for understanding the crystallization process of material as well as the reaction mechanism of catalysis. To meet the requirement of experimental conditions for material synthesis and catalytic reactions, in situ MAS NMR techniques have been continuously developed for using at higher temperatures and pressures with high sensitivity. Herein, we will briefly outline the development of this technology and discuss its detailed applications in understanding material synthesis and heterogeneous catalysis.
