Synthesis of metal–organic-framework related core–shell heterostructures and their application to ion enrichment in aqueous conditions†
Abstract
We show a step-by-step strategy to fabricate MOF related core–shell heterostructures and successfully obtain SiO2@HKUST-1 core–shell nanospheres, which display the distinct ion separation ability of valving the sorption–desorption of fluoride ions by controlling the pH.
