Water adsorption in UiO-66: the importance of defects.
Simulated adsorption isotherms for water in UiO-66 illustrate that defects in the form of missing linkers make this MOF more hydrophilic. Heats of adsorption and density plots further confirm the effect of defects on adsorption of water in UiO-66 at low loadings. In addition, water and CO2 isotherms indicate that not only the amount of defects but their locations within the material affect the ...
متن کاملH2 storage in isostructural UiO-67 and UiO-66 MOFs.
The recently discovered UiO-66/67/68 class of isostructural metallorganic frameworks (MOFs) [J. H. Cavka et al. J. Am. Chem. Soc., 2008, 130, 13850] has attracted great interest because of its remarkable stability at high temperatures, high pressures and in the presence of different solvents, acids and bases [L. Valenzano et al. Chem. Mater., 2011, 23, 1700]. UiO-66 is obtained by connecting Zr...
متن کاملCarbon dioxide adsorption in amine-functionalized mixed-ligand metal-organic frameworks of UiO-66 topology.
A series of mixed-ligand [1,4-benzenedicarboxylic acid (BDC)/2-amino-1,4-benzenedicarboxylic acid (ABDC)] UiO-66 metal-organic frameworks (MOFs) synthesized through two different methods (low (LT) and high temperature (HT)) have been investigated for their carbon dioxide adsorption properties from 0 to 1 bar to clarify the role of amino loading on carbon dioxide uptake. Volumetric CO2 isotherms...
متن کاملOne Step Backward Is Two Steps Forward: Enhancing the Hydrolysis Rate of UiO-66 by Decreasing [OH−]
The rapid destruction of chemical threats, such as phosphate-based nerve agents, is of considerable current interest. The hydrolysis of the nerve-agent simulant methylparaoxon, as catalyzed by UiO-66 and UiO-67, was examined as a function of pH. Surprisingly, even though typical phosphate−ester hydrolysis mechanisms entail nucleophilic attack of the simulant by aqueous hydroxide, the rate of hy...
متن کاملUtilisation of gold nanoparticles on amine-functionalised UiO-66 (NH2-UiO-66) nanocrystals for selective tandem catalytic reactions.
Colloidal deposition of gold nanoparticles (Au NPs) onto NH2-UiO-66 nanocrystals has been demonstrated with the resulting hybrid catalyst proving robust and versatile for one-pot, heterogeneous conversions involving the selective oxidation of primary alcohols in tandem with Knoevenagel condensation reactions. Within these systems, structure-property correlations have been established to confirm...
