The photocatalytic experiments were carried out under UV light and natural sunlight. The synthesis of the thin film photocatalysts was carried out by an electrochemical deposition method and the resulting films were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), UV-Vis spectroscopy, electrochemical impedance spectroscopy and capacitance measurements (i.e., Mott-Schottky plots). Under UV illumination, the results showed that the photocatalytic degradation activity is of first-order kinetics and the lifetime of the photogenerated electron-hole pairs of ZnO is increased by the Cu doping. The combination of Cu-doped ZnO and Cu2O allows the construction of a p-n heterojunction that enhances the photocatalytic process, as demonstrated for the photocatalytic degradation of dyes under sunlight irradiation.
