▎ 摘  要

NOVELTY - A chiral metal-organic framework-magnetic graphene functional material is obtained by dispersing magnetic graphene in a chiral metal-organic framework material. The magnetic graphene comprises a magnetic magnetite core, a silica layer wrapped around the core, and an amino-modified graphene oxide. USE - Chiral metal-organic framework-magnetic graphene functional material is used for rapid selective adsorption of binaphthol enantiomer (claimed). ADVANTAGE - The chiral metal-organic framework-magnetic graphene functional material has excellent chiral recognition ability with respect to binaphthol enantiomer, high selective adsorption capacity, and enantiomeric excess value of 74.8%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of chiral metal-organic framework-magnetic graphene functional material, which involves mixing graphene oxide, magnetic magnetite nanopellets and tetraethyl orthosilicate to form magnetite-silica graphene oxide, ultrasonically-dispersing magnetite-silica graphene oxide in anhydrous toluene, stirring 3-aminopropyltriethoxysilane, heating at 110 degrees C under nitrogen atmosphere for 12 hours, washing, drying to obtain amino-modified magnetic nano-pellets, mixing N-hydroxysuccinimide and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide with amino-modified magnetic nano-pellets, washing, and drying.
