Abstract:

SiO₂/TiO₂ nano-hybrid particles were successfully prepared by hydrothermal method by using titanium tetrafluoride (TiF₄) 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 TiO₂prepared by hydrothermal method were anatase crystal, and in the form of polycrystalline. The formation mechanism of SiO₂/TiO₂ nano-hybrid particles was also discussed.
