High-resolution magic angle spinning (MAS) NMR provides qualitative and quantitative information of solid, liquid, and gas phases at the atomic level, which is vital for understanding material crystallization and catalytic reaction mechanisms in situ/operando conditions. To meet the experimental conditions for material synthesis and catalytic reactions, in situ MAS NMR techniques have been developed with high sensitivity at higher temperatures and pressures. This article briefly outlines the development of this technology and discusses its detailed applications in understanding 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.
