Synthesis of Nano C60-[Fe3O4/SiO2/GeO2] as Efficient Catalyst Disinfection

Abstract

The C₆₀/Fe₃O₄/SiO₂/GeO₂ composite was synthesized containing core/shell/shell nanomaterial by layer/layer gel method. The C₆₀/Fe₃O₄/SiO₂/GeO₂ composite was characterized by X-ray diffraction, field emission scanning electron microscopy fitted through scanning electron microscopy, energy dispersive X-ray spectroscopy, fourier transform infrared spectroscopy, transmission electron microscopy and UV-visible. Magnetic behavior of the synthesized product was evaluated by vibrating-sample magnetometer. The data exhibited that magnetite composites have been properly coated. This system can be applied for recycling photosensitizing way using solar energy for water disinfection. Results were reported and for degradation organic compounds via producing a single oxygen. This approach comprises C₆₀ amino fullerene as a sensitizer for singlet oxygenation and Fe₃O₄/SiO₂/GeO₂ encapsulating magnetite nanoparticles. Fast degradation of furfuryl alcohol and methylene blue under UV-visible light exhibit that this irradiation activity of C₆₀ amino fullerene-derivatives is related to the photosensitization of single oxygen. Significant single oxygen production using C₆₀/Fe₃O₄/SiO₂/GeO₂ system causes the effective oxidation of and inactivation of MS-2 bacteriophage under UV/visible irradiation. Our results also exhibited that the variable surfaces were effective in photo-catalyst behavior of these compounds. C₆₀/Fe₃O₄/SiO₂/GeO₂ composite can also be recovered and reapplied using a strong magnetic field and the photo-catalyst particles again.
