Towards transport-optimized nanostructured porous materials with a hierarchy of pore sizes
S. Vasenkov, Dept. of Chem. Engineering, University of Florida, Gainesville, FL We apply a new NMR experimental option, viz. high field (17.6 T) and high gradient (up to 36 T/m) pulsed field gradient (PFG) NMR, to study diffusion of sorbate molecules in porous materials, which contain interconnected networks of micropores with the pore sizes approaching the sizes of sorbate molecules and of much larger meso- and/or macropores. Our most recent PFG NMR diffusion studies demonstrate a possibility of quantification and fundamental understanding of an interplay of molecular diffusion in different types of pores for a broad range of length scales. This research will help to develop new nanoporous materials with enhanced properties and to optimize already available materials for Mass separations Storage Catalysis
