Abstract:The immobilization of powdery metal-organicframeworks (MOFs) into porous matrix has risen to be a promising approach for their practical applications. This work presents the green synthesis of porous alginate/ZIF-8 composite beads through the in situ growth of ZIF-8 in alginate hydrogel beads crosslinked by Zn 2 + and subsequent freeze-drying process, during which only water is used as reaction solvent. The macro-and meso-pores in alginate matrix and micro-pores in immobilized ZIF-8 endow the porous composite … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
