Hydrothermal Synthesis of Flower-Like CuO/ZnO/SiNWs Photocatalyst for Degradation of R6G under Visible Light Irradiation

摘要：

　　Flower-like CuO/ZnO/SiNWs nanostructures were successfully synthesized on SiNWs substrates using a simple hydrothermal method.The characteristics of the CuO/ZnO/SiNWs nano-structures were investigated through scanning electron microscopy (SEM), X-ray diffraction (XRD), and UV-vis spectrophotometer.SEM images revealed shape transitions when the precursor mass ratic increased from 50∶50 to 5∶95.The strong intensity and narrow width of XRD peaks indicate that CuO/ZnO nanostructures with high molarities have good crystallinity.The UV-vis spectro-photometer indicate that ultraviolet emissions shift slightly toward lower wavelengths with incr-easing precursor solution molarity and that the intensity increases with improvement in CuO/ZnO/SiNWs crystallization.The mechanism of CuO/ZnO/SiNWs for improvement in photocatalytic activity was also discussed.
