Synthesis and characterization of TiO sub(2)-NiO and TiO sub(2)-WO sub(3) nanocomposites

TiO sub(2)-NiO and TiO sub(2)-WO sub(3) nanocomposites were prepared by hydrothermal and surface modification methods. The samples were analyzed using X-ray diffraction, Scanning Electron Microscope images, Transmission Electron Microscope, Energy dispersive analysis, Zeta potential, Electrophoretic mobility and Photocatalysis activity measurement. XRD data sets of TiO sub(2)-NiO, TiO sub(2)-WO sub(3) powder nanocomposite have been studied for the inclusion of NiO, WO sub(3) on the anatase-rutile mixture phase of TiO sub(2) by Rietveld refinement. The cell parameters, phase fraction, the average grain size, strain and bond lengths between atoms of individual phases have been reported in the present work. Shifted positional co-ordinates of individual atoms in each phase have also been observed.
