ABSTRACT=In this paper, MgO@AgO/Ag2O nanoparticles (NPs) were greenly synthesized, the current idea is to replace the harmful chemical technique with an eco-friendly synthesis of metal oxide nanoparticles (NPs) utilizing biogenic sources. The current investigation was conducted to create silver oxide NPs decorated by MgO NPs (namely, MgO@AgO/Ag2O nanocomposite) using the leaves extract of Purslane (Portulaca Oleracea) as the reducing and capping agent. The nanopowder was investigated by means of X-ray diffraction (XRD), scanning electron microscope (SEM), BET surface area, Fourier transform infrared (FTIR), and UV-vis spectrophotometer studies. XRD studies reveal the monophasic nature of these highly crystalline silver nanoparticles. SEM studies the shape and morphology of the synthesis AgO/Ag2O and MgO@AgO/Ag2O NPs. The presence of magnesium and oxygen was further confirmed by EDS profile. The surface area was found to be 9.1787 m²/g and 7.7166 m²/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/Ag2O NPs and MgO@AgO/Ag2O NPs for photocatalytic activity dye degradation (methylene blue and toluidine blue).
