| Abstract: TiO2-SiO2 nanocomposite particles were prepared in premixed H2 / Air flame, and the morphology and structure of these nanocomposites were characterized by FTIR, XRD, TEM and HRTEM. The morphology of SiO2 / TiO2 nanocomposites was different from that of pure TiO2 or SiO2 nanoparticles, and the chemical bond of Ti-O-Si was found in the nanocomposites indicating that the TiO2 / SiO2 nanocomposites were not merely a physical mixture of TiO2 and SiO2. TiO2 nanocrystalline grains with sizes of 1～2 nm were homogeneously dispersed in the amorphous SiO2 matrix when TiCl4 and SiCl4 were mixed at molecular level in the flame. The particle size and rutile content decreased with increasing of SiO2 molar ratio. | |
