Abstract
Implementing a hydrothermal method, ZnO modified copper oxide (CuO) photocatalysts
were developed. The morphology, structure, composition and photocatalysts were examined
using Scanning electron microscopy (SEM), X-ray diffraction (XRD), Energy dispersive
X-ray (EDX), Fourier Transform Infrared Spectroscopy (FTIR) and UV-visible spectroscopy.
The X-ray data confirmed the crystalline nature of CuO. The EDX and FTIR showed
composition of samples as Cu, O and Zn.
Additionally, the effect of zinc oxide impurity on the photocatalytic activity of
CuO nanocatalysts in the methylene blue (MB) process of degradation was investigated
by UV-Visible spectroscopy. The degradation results indicated that ZnO doped CuO
(CuO-ZnO) photocatalysts were more effective in degrading the MB because of their
band gap.
