Water diffusion into ZIF-8 hydrophobic nanopores
Water dynamics in highly hydrophobic nanopores is almost unexplored experimentally but relevant for a large number of confining systems and applications. The Metal Organic Frameworks, ZIF-8 is a promising candidate for such a study because of its large porosity, strong hydrophobicity and water stability. Liquid water is present within the nanopores only above 240 bars. The goal of this proposal is to complete a previous experiment in the aim of quantifying the diffusion coefficients of water confined within ZIF-8 cavities from QENS measurements. This characterization relies on a comparison between measurements at low pressure in presence of bulk water only around nanoporous ZIF-8 particles and measurements at high pressure with both confined water within the nanopores and bulk water around the ZIF-8 particles.
