Cu2O nanowires were successfully synthesized by an electrochemical method using alumina membrane as template.The composition and morphology of nanowires were characterized by using X-ray diffraction(XRD)and scanning electron microscopy(SEM).The photo-potential and electrochemical impedance spectroscopy experiments of Cu2O/AAO were also performed.The results showed that the diameter of the Cu2O nanowires was about 120 nm and their length was 2 μm.The photo-potential was about 25 mV and the electrochemical impedance of Cu2O/AAO was much smaller under the light of 365 nm.
