Amorphous metal-organic frameworks obtained from a crystalline precursor for the capture of iodine with high capacities.

Two amorphous metal-organic frameworks (MOFs) were obtained from crystalline Co-MOF (SCNU-Z6) temperature-induced (-SCNU-Z6) and water-immersed (-SCNU-Z6) approaches. They exhibited high iodine uptake, with the adsorption capacities of -SCNU-Z6 and -SCNU-Z6 reaching 2.05 and 5.
