| Abstract: | CdS nanoparticles were deposited directly into the anodic TiO2 nanotubes via a simple hydrothermal method. The morphology and the structures were characterized by field-emission scanning electron microscopy(FESEM), X-ray diffraction(XRD), energy dispersive spectrometer(EDS) and ~UV-Vis reflective spectrum(UV-Vis). The photoelectrochemical properties of TiO2 and CdS/TiO2 catalysts were studied which indicates that compared with pure TiO2 nanotube catalyst, CdS/TiO2 the photocatalytic activity of CdS/TiO2 composite photocatalyst was improved markedly both under ultraviolet and visible light. |
