ZnO–MnO2–Cu2O triple nanocomposite: Facial synthesis, characterization, visible light photocatalytic performance for dyes degradation

Novel ZnO–MnO2–Cu2O (ZMC) triple nanocomposite (TNC) was synthesized via the facial synthesis method. The ZMC TNC was characterized by UV–vis, FTIR, XRD, and SEM, techniques. The optical activity of the samples was studied via UV–vis analysis. The FTIR spectra confirmed the presence of metal-O bands in sample. The crystalline structure of the sample was studied via XRD pattern. The morphology of the prepared compound (ZMC TNC) was analyzed via SEM images. The presence of Zn, Mn, and Cu in the prepared sample was confirmed via EDS test. The photocatalytic activity of ZMC TNC was examined by degradation of Rhodamine B and Direct Red dyes in visible light. As a result, ZMC TNC degrades dyes considerably quickly. As an important achievement, the present researchers showed that the simple synthesis of TNCs is possible, and also TNCs have high capabilities due to their new, consolidated, triple and combined properties.
