Decoration of Reduced Graphene Oxide with Magnesium Oxide during Reflux Reaction and Assessment of Its Antioxidant Properties

The aim of this work is the reduction and decoration graphene oxide (GO) with magnesium (MgO). In work, GO was synthesized using modified Hummers’ protocol (1:2), (1:3) (1:4) graphite:potassium permanganate mass ratios. Subsequently, all samples (GO1:2, GO1:3, GO1:4) were reduced decorated nanoparticles a reflux technique at 100 °C for 2 h. Sample characterization X-ray diffraction (XRD) reveals presence peaks relative to two different (Mg) phases: (MgO) hydroxide (Mg(OH)2). these spectral features, although characterized by remarkable broadening, confirms successful synthesis Mg(OH)2-rGO-MgO nanocomposites. photoelectron spectroscopy (XPS) spectra indicate assigned C, O Mg. analysis high-resolution XPS elements once again compounds. low temperature nanocomposite exhibiting superior catalytic properties compared MgO–rGO an important step forward respect current state art. antioxidant activity six nanocomposites, namely GO1:2, GO1:4, MgO–rGO1:2, MgO–rGO1:3 MgO–rGO1:4, determined standard protocols based on DPPH radicals scavenging assay, H2O2 phosphomolybdate assay. All our exhibited dose-dependent activity. Interestingly, among nanoparticles, GO1:4 MgO–rGO1:4 showed best performances.
