Abstract:
Metal/metal oxide- reduced graphene oxide nanocomposites are widely and partially used as reaction catalysts, photo catalyst, electrode coats, sensors, adsorbents etc. It is possible to synthesize such nanocomposites adopting eco-friendlier green pathways. In the present work, Zinc Oxide nanoparticles are prepared using Aloe Vera plant extract as the stabilizing agent in mild hydrothermal conditions. Adopting similar conditions, 5 mol% dopant metal ion such as Mg(II), Cu(II), Mn(II), Ni(II) and Sb(II) are included and doped ZnO nps are prepared. powder XRD and HR-TEM measurements are carried out for size determinations. Using modified Hummers method and ultrasonication, graphite powder and doped and undoped ZnO nps are used in the nanocomposite preparations. In this process eco friendlier solvents and mild hydrothermal conditions have been adopted, HR TEM photos of the nanocomposites with undoped and doped ZnO nps are measured.
