In this paper, the TiO2 nanotube (NT) arrays were prepared by anodic oxidation, the preparation con?ditions of HF solution concentration, oxidation voltage and time were optimized, the preparation conditions were rea?sonable. By electrodeposition on TiO2 NT composite a layer of CdS nanoparticles, CdS quantum dot sensitized TiO2 NT, the CdS/TiO2 NT composites, respectively by XRD and SEM were used to characterize the photoelectric conver?sion properties, determination of them under UV light irradiation. The results show that, with the photoelectric con?version of CdS/TiO2 NT composite CdS quantum dot sensitized the efficiency is 6.1660%, is 8 times that of TiO2 NT, significantly improve the photoelectric conversion properties of TiO2 NT.
