Tuning the pore chemistry of Zr-MOFs for efficient metal ion capture from complex streams

Metal-organic frameworks (MOFs) have shown promise for adsorptive separations of metal ions. Herein, MOFs based on highly stable Zr( iv ) building units were systematically functionalized with targeted metal binding groups. Through competitive adsorption studies, it was shown that the selectivity fo...

Description
Summary:Metal-organic frameworks (MOFs) have shown promise for adsorptive separations of metal ions. Herein, MOFs based on highly stable Zr( iv ) building units were systematically functionalized with targeted metal binding groups. Through competitive adsorption studies, it was shown that the selectivity for different metal ions was directly tunable through functional group chemistry. The metal ion adsorption selectivities of stable Zr( iv ) metal-organic frameworks (MOFs) can be readily tuned via functional group chemistry and control of defect character.
