Abstract

Abstract : Three Zr-based MOFs are obtained through steric tuning. The synergistic effect between porous structures and functional groups enhanced the adsorption capacity and adsorption rate for Cr2 O7 2− . Abstract : A ligand with a flexible conformation can be obtained by modifying functional groups. We modified H4 DCBA with –CH3 /–CF3 groups to construct three Zr-MOFs; the torsion of the central benzene ring changes the topologies. The three Zr-MOFs showed high adsorption rates for Cr2 O7 2−, and the CF3 -functional groups enhanced the adsorption capacity of UPC-49 for Cr2 O7 2− .
