In this paper, the uniform ZnO nanorod arrays were prepared by galvanostatic electrodeposition on Ti Substrates. The morphology and structure of samples were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The effects of the concentration of Zn(NO3)2 and the deposition current on the morphology of the ZnO nanorod arrays were investigated. Photocatalytic properties of ZnO nanorod arrays were investigated by degradation of methyl orange (MO) under UV-light irradiation. The analysis revealed that the concentration of Zn(NO3)2 and the deposition current strongly influenced the morphology of the ZnO nanorod arrays. Compared with ITO glass substrates and so on, the uniform and preferable oriented ZnO nanorod arrays could be obtained similarly. The photodegradation rate of ZnO/Ti nanorod electrode was 83.3% during the degradation of methyl orange under 2.5 h of irradiation with UV lamp, which shows good photocatalytic activities. However, the photodegradation rate was only 7% without UV-light irradiation.
