Fabrication and Photoelectrochemical Properties of CuO/TiO2 Heterojunction Nanotubes Array Film
In order to improve the visible light response in titania photocatalysts, CuO/TiO2 heterojunction nanostructures (CuO-TNT) were proposed and fabricated via the electrochemical process. TiO2 nanotubes array (TNT) was first fabricated by secondary anodization, after that the CuO was doped by the electrodeposition. The thin film was characterized by X-ray diffraction (XRD), diffuse reflection spectra (DRS) and field emission scanning electron microscopy (FESEM). Besides, its photoelectrochemical properties were measured in 0.1 M Na2SO3 solution. By comparing the results under different conditions of deposition, it was found that the deposition current density was a crucial parameter for controlling the morphology and the photoelectrochemical properties of the samples.
