Amorphous metal–organic frameworks obtained from a crystalline precursor for the capture of iodine with high capacities†
Abstract
Two amorphous metal–organic frameworks (aMOFs) were obtained from crystalline Co-MOF (SCNU-Z6) via temperature-induced (aT-SCNU-Z6) and water-immersed (aW-SCNU-Z6) approaches. They exhibited high iodine uptake, with the adsorption capacities of aT-SCNU-Z6 and aW-SCNU-Z6 reaching 2.05 and 5.04 g g−1, respectively. This work is the first report of iodine uptake by aMOFs.
