This paper present a review of current research activities of ZnO nanorods (or nanowires, nanotubes). We synthesized ZnO nanowire via template method by the process of Electro deposition. For synthesis of one dimensional nanostructure of Zn, template method has been utilized via a simple two electrode electrochemical cell. The electro deposition has been carried out at a pH around 3.0 and at temperature 32±1 degree. The applied potential between two electrodes was 1.2V.After synthesis ZnO nanowires are characterized with the help of XRD spectra recorded, Energy dispersive X-ray (EDX), Scanning Electron Microscope (SEM); XRD graph also clarifies the polycrystalline nature of synthesized nanowires. The I-V characteristic of pristine nanowires has been drawn by using a 2-probe system via Keithly 2400 series source meter.
