Synthesis, characterization, and antibacterial activity of ZnO–MnO2–Cu2O triple nanocomposite

Novel ZnO-MnO-CuO triple nanocomposite (TNC) was synthesized via the facial synthesis method. For comparison, ZnO-MnO (ZM) and ZnO-CuO (ZC) nanocomposites (NCs) were prepared. The prepared samples were characterized by, FTIR, and SEM, techniques. The FTIR spectra confirmed the presence of metal-O bands in samples. The morphology of the prepared compounds was analyzed via SEM images. The antimicrobial activity of ZMC TNC, ZnO-MnO NC, and ZC NC displayed a high activity against the common pathogens Escherichia coli (E. coli, ATCC 9637) and Staphylococcus aureus (S. aureus, ATCC 12600) especially in the case of ZMC TNC. ZMC triple nanocomposite shows considerably more activities than NCs. As a result, triple nanocomposites can be employed in different biological, environmental, electrical, and optoelectronic applications. As an important achievement, the present researchers showed that the simple synthesis of triple nanocomposites is possible, and also triple nanocomposites have high capabilities due to their new, consolidated, triple and combined properties.
