Synthesis and characterization of ZnO/CuO

2017-1-1  Conclusion. In this article, electrochemical method was used for synthesis of ZnO/CuO nanocomposite. Incorporation of monoclinic CuO within hexagonal wurtzite ZnO has been confirmed by XRD and EDX analysis. UV-DRS analysis exhibited that ZnO has a maximum reflectance of ~55% which decreased to ~35% in ZnO/CuO.
