Abstract- Synthesis of CuO nanowires was performed on waste electrical copper wire in wet air and nitrogen ambience at 400 and 500C. We found that nanowires formed in the wet air but not in the nitrogen ambience. Diameters of the synthesized nanowires are between 30 to 160 nm and lengths are up to 39 m. SEM images show that CuO nanowires were formed on top of the oxide grains. Vapor–solid growth mechanism is suggested for the growing this type of nanowires.

Keywords: CuO nanowire, vapour-solid growth
