文摘

ZnO nanorods were prepared on fluorine doped tin oxide (FTO) using the electrodeposition method. The architecture of the ZnO nanorods arrays was strongly modified by addition of TiO₂ nanoparticles during the electrodeposition process. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to characterize their morphology and structure and confirmed the successful formation of ZnO nanorods. The ZnO-TiO₂ modified electrodes demonstrated an increase of the photocurrent activity under enhanced UV white light irradiation. This was attributed to the increased surface area and therein the photoactive surface area.
