摘要：

ZnO nanorods arrays (ZNAs) with hexagonal structures were elaborated on fluorine doped tin oxide (FTO) using a recurrent cyclic voltamperometry technique. Their XRD patterns show an hexagonal structure type Wurtzite with a preferential orientation along the axis (002). Their transparency increases with the enhancement of the sweeping rate. The insertion of TiO2 nanoparticles during the electrodeposition strongly affected the ZNAs morphology, orientation and size. Its addition led to a greater compactness and well tightly arranged nanorods with important increasing generated photocurrents under illumination. It led also to the reduction of the optical gap layers of ZnO. The SEM analysis revealed that TiO2 presents spherical orbicular nanostructures with smaller size than the ZNAs. (C) 2014 Elsevier Ltd.
