Synthesis and characterization of the leaf-like Cu2O/CuO mixed phase nanosheets array

摘要

In this study, a leaf-like Cu2O/CuO mixed phase nanosheets array was successfully prepared by anodization. XRD, EDS, and XPS analysis confirmed the formation of Cu2O/CuO mixed phase nanostructures. SEM images indicate that the fabricated Cu2O/CuO mixed phase nanosheets almost grow vertically on the substrate. The average height of nanosheets is approximately 500?nm. The optical absorption of the mixed phase covers the entire wavelength region of visible light and a little part of the near-infrared region of short wavelength.
