SBA and KIT-6 Mesoporous Silica Magnetite Nanoparticles: Synthesis and Characterization

Abstract

In the present study, simple and versatile methods for preparation of SBA-3, SBA-15, and KIT-6 mesoporous silica magnetite nanoparticles (Fe3O4@SBA and Fe3O4@KIT-6 MNPs) were developed. The chemically synthesized magnetite nanoparticles were utilized for preparation of mesoporous MNPs with Fe3O4 core and mesoporous silica (SBA-3, SBA-15, and KIT-6) shell. The size and chemical structures of the synthesized nanoparticles were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared spectrophotometery (FT-IR). The synthesized mesoporous MNPs showed super paramagnetic property and the surface area of synthesized Fe3O4@SBA-3, Fe3O4@SBA-15, and Fe3O4@KIT-6 via BET was obtained as 627.87, 510.95, and 241.68 m2 g−1, respectively.
