摘要：
Cu2O/Cu nanocomposites with flowerlike nano-architecture were prepared using a template-free two-step hydrothermal synthesis route. The phase-structure, morphology and specific surface area were characterized by the X-ray differction (XRD), scanning electron microscope (SEM), high resolution transmission electron microscope(HRTEM) and automatic adsorption. The photocatalytic property of the composite catalyst was characterized by phtodegradation on Procion Red MX-5B under visible-light illumination. Compared with Cu2O and P25, the flowerlike Cu2O/Cu nanocomposites exhibit higher photocatalytic performance on photo-degradation of Procion Red MX-5B under visible-light illumination due to the interaction between Cu2O and Cu, indicating that they are good candidates for the processing of pollutants.
