Abstract A series of ZnO/CNTs composite samples were prepared by hydrothermal method. The influence of CNTs content on the photocatalytic properties of ZnO/CNTs composites were investigated in detail. The crystalline structures, morphologies and light absorption properties of the ZnO/CNTs composites were analysed using X-ray diffractometer, UV-vis spectrophotometer, scanning electron microscopy, X-ray energy dispersive spectroscope, transmission electron microscopy, X-ray photoelectron spectroscopy and N₂ adsorption-desorption measurement, respectively. In this work, methylene blue was used as the model substance to evaluate the photocatalytic activity of ZnO/CNTs composites. The results showed that the addition of CNTs could enhance BET surface area and light absorption in visible light region of ZnO. Compared to pure ZnO, the photocatalytic efficiencies of ZnO/CNTs composites were greatly improved. In addition, with the increase of CNTs content, the photocatalytic efficiencies of ZnO/CNTs composites increase firstly and then decrease. The best performance is achieved with the ZnO/CNTs composites containing 0.3wt% CNTs, and the photocatalytic degradation of methylene blue achieves 96.2% in 50 min under the irradiation of light.
