Development and Application of ssNMR Technique

To tackle the persistent challenges of sensitivity and resolution in ssNMR observations, the focus is on designing multi-dimensional, multi-nuclear SSNMR experimental pulse methods under high magnetic fields and high-speed magic angle spinning. This approach aims to significantly enhance the observation efficiency of vital nuclides (such as quadrupolar nuclei 27Al, 67Zn, 95Mo, 17O) in heterogeneous catalytic materials. These advancements enable to gain more detailed insights into the structure and dynamics of these materials, ultimately contributing to the development of more efficient and sustainable catalytic processes.
