1H MAS NMR Study of Water on Pd-MCM-41
(University of Waterloo, 2015-06-18)Hydrogen spillover represents one of the most promising avenues to achieve hydrogen storage at the density required for transportation applications. The spillover phenomenon, however, is a topic of much debate, with many ... -
¹H MAS NMR Spectral Coalescence of Water and Hydroxyl Resonances in MCM-41
(University of Waterloo, 2011-09-01)Solid state ¹H MAS NMR spectroscopy was used to investigate the temperature and hydration dependance of water and hydroxyl proton spectra of hydrated mesoporous MCM-41. The NMR spectra show a complex peak structure, with ... -
NMR STUDY OF EXCHANGE AND HYDRATION SITE IDENTIFICATION IN MCM-41
(University of Waterloo, 2007-01-16)Deuteron 1D and 2D NMR spectroscopy was used to study the dynamics of water molecules within the mesoporous material MCM-41. The deuteron spectra show three magnetization components for a sample hydrated to a 0.2 monolayer ...
