abstract
Solvent-assisted linker exchange (SALE) is performed on the Zr-based metal-organic framework (MOF), UiO-66, to exchange benzene-1,4-dicarboxylate with benzene-1,4-dihydroxamate linkers. Characterization of the material before and after SALE is performed using powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), nitrogen adsorption, diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and thermogravimetric analysis (TGA). The stability of the parent and daughter material is evaluated at pH 1 and 12 and the structural integrity evaluated by PXRD, mass balance and porosity measurements.
