摘要：In this project, a facile convenient and Frugal method of sol-gel assisted hydrothermal method was used for the synthesis of pure FeO NPs. The structural and optical morphology are inspected using various techniques of the synthesized nanoparticles and at different molar concentrations of 1, 2 and 3 moles respectively. The crystallographic morphology of the synthesized particles was studied via X-ray diffraction which revealed Rhombohedral structure of the, pure FeO NPs and the crystal size is noted to be increasing with the increase in concentration. The Scanning Electron Microscope (SEM) demonstrates the crystalline growth being proportional to the concentration of nanoparticles. The Fourier Transform Infrared Spectroscopy (FTIR) confirmed the presence of various functional groups such as O-H, C-O, C=O, and C-N groups. The elemental composition studied using EnergyDispersive X-Ray Spectroscopy (EDX) revealed the presence of Fe and O particles and the purity of FeO NPs were noted. Optical characterization of the sample using UV-Vis-NIR Spectroscopy revealed the band gap (E) being decreased from 6.2eV to 4.7eV with the increase in molar concentration of FeO NPs. Anti-Bactericidal of the NPs was assessed at pre-defined concentrations (25 and 100 μg /ml) against Gram +ve bacteria Staphylococcus aureus, Gram −ve bacteria Fungi Candida and Escherichia coli. Bacterial strains, which demonstrate the potential of NPs. The goal of this research was to see how the structure of the synthesized NPs affected their ability to guard against harmful bacterial activities.
