Abstract

In this study, porous nanostructured ZnO-CuO photocatalyst was successfully prepared. Samples were fabricated through a simple one-step brass anodizing method in alkaline aqueous solution (0.1 M NaOH and 0.025 M NH4Cl). The process was taken place under the constant voltage (12 V), room temperature and, at different time of 30 minutes. The as-prepared sample were characterized by X-ray diffraction (XRD), field emission electron microscope (FESEM) and energy dispersive spectroscopy (EDS). XRD results confirm the existence of copper oxide (CuO) and zinc oxide (ZnO) with average crystallite sizes of 300 and 47 nm, respectively. The EDS results shows that the ZnO-CuO atomic percentage ratio is about 0.2. The FESEM result reveals that CuO has a flake like structure and ZnO has a rosette like structure and finally photocatalys analysis under visible light irradiation revealed that more than 40% of MB dye can be degraded after 5 hours.
