Abstract
Introduction:
In this paper, MgO@AgO/Ag
2
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
2
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

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

/g and 7.7166 m
2
/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
