Deposited Films

Well-defined cuprous oxide (Cu2O) thin films can be electrodeposited from an electrolyte containing copper (II) sulfate, lactic acid and sodium hydroxide. As Cu2O is a p-type semiconductor, it is possible to accelerate the process through illumination with light of sufficient energy (>2.1eV). Cyclic voltammetry and transient potentiostatic measurements were performed in a three-electrode setup with copper metalized wafers as a working electrode. Illumination was performed through the electrolyte, therefore absorption of light by the electrolyte had to be taken into consideration. Potentiostatic measurements with a blue LED as a light source have shown an tenfold increase in layer thickness in comparison to depositions without additional illumination. The deposited films were investigated with SEM analysis.

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.
