The nanoscale CuO/ZnO composite photocatalysts were prepared via the wet chemical route. The detailed structural and physico-chemical properties of the obtained products were analyzed by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-Vis spectroscopy, FT-IR spectroscopy and fluorescence spectra. The vis i ble-light photocatalytic activity of CuO/ZnO nanocomposite was evaluated by employing the photodegradation of dye molecules (methyl orange, MO) as a probe reaction in aqueous solution. The effects of various parameters such as catalyst dosage and pH value of suspension on photocatalytic degradation efficiency of MO were investigated. The results indicate that the photocatalytic activity of CuO/ZnO nanocomposite is much better than that of commercial TiO2 photocatalyst and the photocatalytic ability of nanocomposite is almost not decreased after a four-cycle degradation of MO.
