Porous millimeter-sized MOF-808@PVDF composite beads with ultrahigh iodine adsorption capacity for capture of radioiodine from gas streams.
Alginate (ALG)–lysozyme (LZ) beads were fabricated by a cross-linking process. Negatively charged ALG and positively charged LZ were alternately deposited on the positively charged ALG–LZ beads via a layer-by-layer (LBL) self-assembly technique.
