Abstract

Two amorphous metal-organic frameworks (aMOFs) were obtained from crystalline Co-MOF (SCNU-Z6) via temperature-induced (a_T-SCNU-Z6) and water-immersed (a_W-SCNU-Z6) approaches. They exhibited high iodine uptake, with the adsorption capacities of a_T-SCNU-Z6 and a_W-SCNU-Z6 reaching 2.05 and 5.04 g g^-1, respectively. This work is the first report of iodine uptake by aMOFs.
