Pore Structure Characterization of Mesoporous/Microporous Materials by 1H NMR Using Water as a Probe Molecule

Model improvements related to the analysis of 1H NMR signal intensity vs temperature (IT-curve) of a fluid confined in porous materials are presented enabling pore size distribution, specific surface area, and relative distribution of pore volumes to be extracted. The model is applied to four differ...

Description
Summary:Model improvements related to the analysis of 1H NMR signal intensity vs temperature (IT-curve) of a fluid confined in porous materials are presented enabling pore size distribution, specific surface area, and relative distribution of pore volumes to be extracted. The model is applied to four different porous materials, two containing mesopores only and two containing both mesopores and micropores.
