Fabrication and Characterization of SiO2/TiO2 Nano-Hybrid Particles

摘要：

　　SiO2/TiO2 nano-hybrid particles were successfully prepared by hydrothermal method by using titanium tetrafluoride (YiF4) as the titanium source, silicon dioxide as template.The factors of hydrothermal temperature and hydrothermal time on the morphologies and photocatalytic activity of SiO2/TiO2 nano-spheres were systematically discussed in this paper.The structures and properties of the SiO2/TiO2 nano-hybrid particles were studied by some techniques such as SEM, TEM, XRD and BET analysis.The results indicated that TiO2 prepared by hydrothermal method were anatase crystal, and in the form ofpolycrystalline.The formation mechanism of SiO2/TiO2 nano-hybrid particles was also discussed.
