Double hydrothermal synthesis of iron oxide/silver oxide nanocomposites with antibacterial activity

In this work, iron oxide "gamma phase" (gamma-Fe2O3)-silver oxide (Ag2O) nanocomposite is prepared by a double hydrothermal method combined with Punicaceae plant extract as reducing agents. X-ray diffraction (XRD) results confirmed the presence of gamma-Fe(2)O(3)and Ag2O and delafossite silver ferrite (AgFeO2) phases. Field Emission Scanning Electron Microscopy-energy dispersive spectroscopy (FESEMEDS) results revealed nanoparticles (NPs) with a shape like a cauliflower plant. Furthermore, the anti-bacterial activity results presented high inhibition rates against Klebsiella pneumoniae , Staphylococcus aureus , Staphylococcus epidermidis , Escherichia coli , and Candida albicans. The present study exhibits a new approach to the preparation of metal oxides using a facile and inexpensive method.
