We report on the synthesis, morphology, chemically and structurally of SiO2 -TiO2 nanostructure. The SiO2 -TiO2 nanostructure was synthesized by a method based on the sol-gel method. In the present work, binary reactive powders in the SiO2 -TiO2 systems have been obtained using the sol-gel method, by the simultaneous gelation of all cations. Composite powders and coating on glass have been characterized by XRD, XRF, SEM and FTIR. X-ray diffraction showed the formation of nano crystalline anatase and rutile phases. Scanning electron microscopy revealed that aggregation structure formed by increasing the calcinations temperatures. The weight percent of ingredient in production was obtained by using XRF. The average crystallite size was calculated by using X-ray diffraction analysis. FTIR spectra showed that Ti-O-Si, O-Si-O and Si-O-Si bonds are formed and indicated that titanium is in four-fold coordination with oxygen in the SiO4-. The effects of chemical compositions and the strong process on the surface topography and the crystallization of anatase were studied.
