Abstract

The Cu/ZnO nanocomposites with different Cu content of 20 wt%, 40 wt%, 60 wt% and 80 wt% were synthesized via chemical deposition method. The structure, morphology and optical properties of Cu/ZnO nanocomposites were characterized by X-ray diffraction, field emission scanning electron microscopy and ultraviolet-visible spectroscopy. The photocatalytic activity for degradation of methyl orange (MO) revealed that the Cu/ZnO nanocomposites have markedly improved visible light photocatalytic performance than the pure ZnO. The enhanced photocatalytic performance was correlated with the interface between ZnO and Cu nano particles. The ideal Cu content turned out to be 60 wt%..
