Abstract Nanocomposites of CuO/ZnO were synthesized with cetyltrimethylammonium bromide as a growth regulator by one-step hydrothermal method. The catalyst was characterized by X-ray diffractometry (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), fluorescence spectrometer (FL) and UV-Vis spectrometer (UV-Vis). The photocatalytic effect of the composite photocatalyst with different ratios of CuO to ZnO on the degradation efficiency of methyl orange under ultraviolet light irradiation, and the cyclic stability of the composite photocatalyst were investigated. The results show that CuO/ZnO photocatalysts are mainly composed of CuO nanoparticles and ZnO nanosheets. The proper amount of CuO can effectively adjust the light absorption performance of ZnO and enhance the efficiency of ultraviolet photocatalysis. Excess CuO (?7%) has inhibitory effect on ZnO ultraviolet catalytic efficiency. CuO/ZnO has good stability in the photocatalytic process.
