A high recombination rate and low charge collection are the main limiting factors of copper oxides (cupric and cuprous oxide) for the photocatalytic degradation of organic pollutants. In this paper, a high performance copper oxide photocatalyst was developed by integrating cupric oxide (CuO) and cuprous oxide (Cu2O) thin films, which showed superior performance for the photocatalytic degradation of methylene blue (MB) compared to the control CuO and Cu2O photocatalyst. Our results show that a heterojunction photocatalyst of CuO–Cu2O thin films could significantly increase the charge collection, reduce the recombination rate, and improve the photocatalytic activity.

Cu2o Thin Films

Cuprous oxide films are successfully electrodeposited through the reduction of cupric ions in alkaline and acid electrolytes. The effect of electrodeposition parameters on the optical band gaps of Cu2O films is investigated using UV-vis spectroscopy. It is found that the optical transmittances and the band gaps of the Cu2O thin films are strongly influenced by the electrodeposition bath, the temperature, the current density, and the pH value. The band gaps are varied from 1.80 eV to 2.43 eV with different electrodeposition parameters.
