Abstract

Titania nanotube arrays were prepared by titanium anodizing, then CdS/TiO₂ nanotube arrays composite photocatalysts were prepared by an AC electrodeposition method for different times. The morphology and crystal structure of the CdS/TiO₂ composite photocatalysts were characterized by SEM and XRD. The photoelectrochemical properties of the composites were investigated by means of UV-visible absorption spectra and photocurrent measurements. The photocatalytic activity was evaluated by the degradation of methyl orange under UV-visible light irradiation. The results show that there is an optimum deposited time for the highest photocatalytical activity of the CdS/TiO₂ composite photocatalysts under UV-visible light irradiation and the optimum deposited time is determined to 3 min.
