Title: Hydrothermal synthesis of TiO{sub 2}-ZnO-graphene nanocomposite towards photocatalytic and photovoltaic applications

Titanium dioxide (TiO{sub 2}) - Zinc oxide (ZnO) - Graphene (G) nanocomposite was successfully synthesized through facile hydrothermal method. The X-ray diffraction (XRD) pattern and the micro-Raman spectroscopic technique revealed the formation of TiO{sub 2}-ZnO-Graphene (TZG) nanocomposite. The ZnO and TiO{sub 2} nanoparticles decorated graphene sheets were clearly noticeable in the Field Emission Scanning Electron Micrograph (FE-SEM). The UV-Visible absorption spectra clearly indicated that the formation of TZG nanocomposite enriched the absorption in the visible region. Hence, the prepared nanocomposite can be used as photocatalyst to remove organic dyes from water and as photoanode in the fabrication of dye sensitized solar cells (DSSCs)
