The Controlling Synthesis and Photocatalytic Activity of Carbon Nanotubes Loaded with CdS Composites under Simulated Sunlight

Abstract:

The CdS/CNTs nanocomposites were prepared by a simple heating refluxing method, and the scattering of CdS on CNTs surface was controlled by a dropping way. The samples were characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM) and ultraviolet-visible diffuse reflectance spectroscope (UV-Vis) .The photocatalytic activity of the samples was tested in the degradation of Methylene blue dye wasterwater under simulated sunlight with 500w short arc xenon lamp. The results showed that the photocatalytic activity of CdS/CNTs composites was enhanced by controlling CdS scatter on CNTs surface, and the forbidden band width was appropriate lowered when CNTs was added, and the scatter of CdS on CNTs surface was uniform and the photocata-lytic activity was the highest when the mass ration of CdS with CNTs was 4:1.The CdS composites have good stability and potential industrial application.
