Abstract

ZnO-TiO2-SiO2 nanocomposites were synthesized by sol-gel technique. Nanocomposites were annealed at 400 °C. The structural and optical characterization was performed by XRD, TEM, FTIR and UV-visible spectroscopic techniques. Average particle size of ZnO-TiO2-SiO2 nanocomposites was found to be 34.23 nm using XRD technique. The energy band gap of ZnO, TiO2 and ZnO-TiO2-SiO2 were found to be 3.4, 3.6 and 3.5 eV, respectively.
