Concocting of FeO nanoparticles by coalescence of metal oxides for supercapacitor applications

Abstract

Iron oxide (FeO) nanoparticles have gained considerable interest from researchers over the past few decades and have a massive effect on wave absorption materials, magnetic fluid, adsorbent, and a variety of industrial applications. In this study, ferric nitrate, sodium hydroxide, and ammonium hydroxide coalesced to form FeO nanoparticles using the chemical co-precipitation approach. X-ray powder diffraction (XRD), scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FTIR), UV-VIS analysis, Photoluminesence (PL) spectrum analysis, and electrochemical measurements were used to characterize FeO nanoparticles. As per XRD, the sample’s crystallite size was 22.63[Formula: see text]nm and 22.64[Formula: see text]nm after it was annealed at 300∘C and 400∘C, respectively. Utilizing XRD, the diffraction patterns were seen. The particles appear to have a fine surface and smooth shape, as seen by SEM photographs. For the detection of FeO nanoparticles, optical and electrochemical examinations were carried out.
