Abstract

Introduction: In this paper, MgO@AgO/Ag <subscript>2</subscript> O nanoparticles were greenly synthesized, the current idea is to replace the harmful chemical technique with an ecofriendly synthesis of metal oxide nanoparticles (NPs) utilizing biogenic sources. Methods: The current investigation was conducted to create silver oxide NPs decorated by MgO NPs (namely, MgO@AgO/Ag <subscript>2</subscript> O nanocom-posite) using the leaves extract of Purslane ( Portulaca Oleracea ) as the reducing and capping agent. The nanopowder was investigated by means of X-ray diffraction, scanning electron mi-croscope, BET surface area, Fourier transform infrared, and UV-vis spectrophotom-eter studies. XRD studies reveal the monophasic nature of these highly crystalline silver nano-particles. SEM studies the shape and morphology of the synthesis AgO/Ag <subscript>2</subscript> O and MgO@AgO/Ag <subscript>2</subscript> O NPs. The presence of magnesium and oxygen was further confirmed by EDS profile. Results and discussion: The surface area was found to be 9.1787 m <superscript>2</superscript> /g and 7.7166 m <superscript>2</superscript> /g, respectively. FTIR analysis showed the presence of specific functional groups. UV-vis spectrophotometer studies show the absorption band at 450 nm due to surface plasmon resonance. The results have also indicated the high performance of the greenly synthesized AgO/Ag <subscript>2</subscript> O NPs and MgO@AgO/Ag <subscript>2</subscript> O NPs for photocatalytic activity dye degradation (methylene blue and toluidine blue).<br />Competing Interests: Author FM was employed by the company Fluorotronics, Inc.-California Innovations Corporation. The remaining authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.<br /> (Copyright © 2022 Zidane, Laouini, Bouafia, Meneceur, Tedjani, Alshareef, Almukhlifi, Al-Essa, Al-Essa, Rahman, Madkhali and Menaa.)
