摘 要: | Fe3O4@SiO2-NH2-CMC magnetic nanoparticles(MNPs) could be prepared by covalent modification method via the modification of sodium carboxymethyl cellulose (CMC). IR spectra could be used for the determination of Fe3O4@SiO2-NH2, Fe3O4@SiO2-NH2-CMC, Fe3O4@SiO2-NH2-CMC/MOF5, and Fe3O4@SiO2-NH2-CMC/IRMOF3 nanoparticles. The results showed that the polysaccharide modification and core-shell modification were successful. Knoevenagel condensation experiments exhibited that, as forFe3O4@SiO2-NH2-CMC/IRMOF3, the best conversion rate could be obtained.
