Stability of MOFs in water with ssNMR | Dr. Frederique Pourpoint | Session 111

During the 111th session of the Global NMR Discussion Meetings held on November 18th, 2025, via Zoom, Dr. Frederique Pourpoint from the University of Lille, France, gave a talk on the topic "Stability of MOFs in the presence of water by solid-state NMR". The recording serves as a tutorial. Find out more about Dr Frederique Pourpoint's research : https://uccs-old.univ-lille.fr/index.... Abstract: The stability of MOFs in the presence of water is a key factor for their performance in numerous applications. We demonstrated that quadrupolar nuclei like 17O and 91Zr offer unique insight into the inorganic cluster of MOFs such as Zirconium-based UiO-66, despite the low natural abundance of 17O and the ultra wide line of 91Zr spectra.
