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

Abstract

The C-60/Fe3O4/SiO2/GeO2 composite was synthesized containing core/shell/shell nanomaterial by layer/layer gel method. The C-60/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 C-60 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 C-60 amino fullerene-derivatives is related to the photosensitization of single oxygen. Significant single oxygen production using C-60/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. C-60/Fe3O4/SiO2/GeO2 composite can also be recovered and reapplied using a strong magnetic field and the photo-catalyst particles again.
