摘要

本文研究了1次、2次、3次包封的TiO2-SiO2-Fe3O4核壳纳米粒子(本文分别命名为TSF1、TSF2和TSF3)的不同性质。通过碳还原法和溶胶-凝胶法制备了TSF纳米颗粒。采用透射电镜(TEM)、x射线衍射(XRD)、振动样品磁强计(VSM)和BET表面积对TSF1、TSF2和TSF3的性能进行了表征。结果表明，TSF2具有较好的性能。TSF1、TSF2和TSF3的辐照时间与脱色率的关系表明，TSF2在紫外光下对甲基橙的脱色效果显著。

Investigation of TiO2-SiO2-Fe3O4 core-shell nanoparticle properties with different functional layer thickness

This paper investigates different properties of the TiO2-SiO2-Fe3O4 core-shell nanoparticles encapsulated for 1 times, 2 times, 3 times (which are named as TSF1, TSF2 and TSF3 in this paper). The TSF nanoparticles were obtained through carbon reduction method and sol-gel method. The properties of the TSF1, TSF2 and TSF3 were characterized by Transmission Electron Microscope (TEM), X-ray Diffraction (XRD), Vibratory Sample Magnetometer (VSM) and BET surface areas. The results show that the TSF2 exhibited better property than the others. The relationships between the irradiation time and decoloration rate of the TSF1, TSF2 and TSF3 indicate that the TSF2 has significant efficiency in decolorating the methyl orange under ultraviolet light.
