Abstract: Using copper chloride (CuCl2·2H2O) and sulfur powder (S) as raw materials,and a mixture of ethanol (C2H6O) and water as solvent,a semiconductor composite composed of several morphologies of Cu7S4 and CuO was successfully prepared by reaction at 180℃ for 24 hours.The products were characterized by XRD,SEM and EDS.The xenon lamp was used to simulate sunlight to investigate the degradation effect of Cu7S4/CuO semiconductor composites on rhodamine B solution.The results shown that the products synthesized by the hydrothermal method had good crystallinity.With the decrease of water consumption,the morphology changed from granular to micro-nanowires.Photocatalytic degradation experiments shown that the micro-nano-wire Cu7S4/CuO composites had better catalytic performance,the degradation rate of rhodamine B was more than 95% in 20 minutes.
