- Amino-functionalized magnetite/Silica (Fe3O4/SiO2) nanoparticles were synthesized in water-in-oil microemulsion system by one-pot process. The structure composition and the surface functional groups of the product were characterized. The synthesized product was embedded structure of Fe3O4/SiO2 nanocomposites with an average diameter size of 12 nm. These magnetic silica nanocomposites with a functional surface had excellent superparamagnetic properties. Accordingly, the amino-functionalized Fe3O4/SiO2 nanocomposites were used as magnetic separation carriers for immobilization of catalase (CAT). The immobilized CAT obtained through covalent attachment exhibited higher resistance of pH and thermal stability than the free CAT. The immobilized CAT still retained a high activity after 10 repeated batches reaction.
