Abstract :
We prepared ZnO/TiO2 nanotubes (TNTs) composite via a two-step route. First, the highly ordered TNTs was prepared by anodization. Then different morphology of ZnO nanostructures were deposited on the surfaces of TNTs by cathodic electrodeposition method. With increasing of the deposition voltage, the morphology of the deposited ZnO nanostructure was gradually changed from nanoparticles to nanocotton and nanodonga. Increasing the deposition time, from nanoflower to puff nanorod of the deposited ZnO nanostructure was successfully achieved. The morphology and crystallinity of nanocomposites were studied by SEM and XRD. Photocurrent response was measured in 0.01M Na2SO4 under the UV-Vis illumination.
