In this study, green synthesis of silver /silver oxide nanoparticles was successfully prepared from Phoenix Dactylifera L aqueous leaves extract. The effect of different volume ratio (% v/v) (Plant extract / Precursor) on the nanoparticles silver /silver oxide nanoparticles formation, optical properties, and catalytic activity for dye degradation was studied. The obtained Ag/Ag2O nanoparticles were characterized using various techniques, such as UV-Visible, FT-IR, XRD, SEM for this purpose. The UV-Vis spectrum shows the absorption at 430 nm associated with Ag/Ag2O NPs. The optical bandgap values were found to be in the range of 3.22 to 4.47 eV for the direct bandgap and 3.73 to 5.23 eV for the indirect bandgap. The functional groups present in plant extracts were studied by FTIR. XRD confirmed the crystalline nature of Ag / Ag2O NP, and its average particle size was between 28.66-39.40 nm. SEM showed that the green synthesized silver/silver oxide nanoparticles have a spherical shape. The purpose of this study, it highlights the high catalytic activity for dye degradation of Ag/Ag2O NPs green synthesized. As a result, the use of Phoenix Dactylifera L aqueous leaves extract offers a cost-effective and eco-friendly method.
