In Situ Neutron Diffraction of Zn-MOF-74 Reveals Nanoconfinement-Induced Effects on Adsorbed Propene
Abstract
Even though confinement was identified as a common elementof selectivecatalysis and simulations predicted enhanced properties of adsorbateswithin microporous materials, experimental results on the characterizationof the adsorbed phase are still rare. In this study, we provide experimentalevidence of the increase of propene density in the channels of Zn-MOF-74by 16(2)% compared to the liquid phase. The ordered propene moleculesadsorbed within the pores of the MOF have been localized by in situneutron powder diffraction, and the results are supported by adsorptionstudies. The formation of a second adsorbate layer, paired with nanoconfinement-inducedshort intermolecular distances, causes the efficient packing of thepropene molecules and results in an increase of olefin density.
