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.

合成纳米 C60-[Fe3O4/SiO2/GeO2]作为高效消毒催化剂

摘要采用层/层凝胶法合成了含有核/壳/贝壳纳米材料的C60/Fe3O4/SiO2/GeO2复合材料。通过 X 射线衍射、场发射扫描电镜、能量色散 X 射线光谱、傅立叶变换红外光谱、透射电镜和紫外可见光对 C60/Fe3O4/SiO2/GeO2 复合材料进行了表征。通过振动样品磁力计对合成产品的磁性进行了评估。数据显示，磁铁矿复合材料已被适当涂覆。该系统可用于利用太阳能进行水消毒的循环光敏方式。报告了通过产生单一氧气降解有机化合物的结果。这种方法由 C60 氨基富勒烯作为单线态氧的敏化剂和封装磁铁矿纳米粒子的 Fe3O4/SiO2/GeO2 组成。在紫外可见光下糠醇和亚甲基蓝的快速降解表明，C60 氨基富勒烯衍生物的这种辐照活性与单线态氧的光敏化有关。利用 C60/Fe3O4/SiO2/GeO2 系统产生的大量单氧在紫外/可见光照射下可有效氧化和灭活 MS-2 噬菌体。我们的研究结果还表明，可变表面对这些化合物的光催化行为非常有效。C60/Fe3O4/SiO2/GeO2复合材料还可以利用强磁场和光催化剂颗粒回收并重新应用。
