| Abstract: | A highly efficient photoelectrocatalytic course was realized by combining TiO2 and CdS films. The TiO2 films were prepared using dc reactive magnetron sputtering method, and the CdS films were deposited by chemical bath deposition (CBD) method. The X-ray diffraction (XRD), Raman, field-emission scanning electron microscope (FESEM) were used to characterize the film structure and surface morphologies. The experiment results showed that the photoelectrocatalysis by using the TiO2 and CdS films under double-beam irradiation of UV and visible lights had higher photocatalytic activity than the sum of photoelectrocatalysis solely using TiO2 and CdS films. |
