Abstract
Abstract In this work, iron oxide "gamma phase" (γ-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 γ-Fe2O3 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.
Highlights
Nanostructures have attracted unparalleled interest due to their unusual properties that differ greatly from their bulk state due to the increased surface area to volume ratio that increases the reactivity of surface electrons in materials [1]

Summary
Nanostructures have attracted unparalleled interest due to their unusual properties that differ greatly from their bulk state due to the increased surface area to volume ratio that increases the reactivity of surface electrons in materials [1]. It was suggested that the phytochemicals are affected directly in the reduction of ions and the creation of NPs. The active compound present in the plant extract reduces the monovalent metal ion to uncharged atoms that aggregate to reach nano-size [15, 16]. The Punicaceae plant extract contains many active compounds maybe acts as a reducing agent to formation NPs, such as ascorbic acid (C6H8O6), gallic acid (C7H6O5), and flavonoe (C15H10O2) [17, 18, 19]. The current study aims to (i) fabrication of γ-Fe2O3-Ag2O nanocomposite by inexpensive hydrothermal method and Punicaceae plant extract as reducing agents (ii) characterizing the optical, structural and morphological properties of the nanocomposite (iii) study the anti-bacterial activity of nanocomposite against gram-positive negative bacteria and gram-positive fungi cultures. 208 | Rahmah et al.
