Abstract
Silver oxide nanoparticles (Ag 2 O NPs) were prepared using cantaloupe ( Cucumis melo ) seeds as a fuel by employing a green synthesis method. The prepared Ag 2 O NPs were investigated using powder X‐ray diffraction (PXRD), UV–visible spectrum, Fourier transform infrared analysis, transmission electron microscopy (TEM), scanning electron microscopy (SEM) with energy‐dispersive spectroscopy, and photoluminescence studies. PXRD data reveal the establishment of cubic crystal structure of Ag 2 O NPs. According to SEM and TEM results, the morphology of the prepared NPs was agglomerated and spherical. The photodegradation activity of the prepared Ag 2 O NPs over methylene blue dye was promising under visible light irradiation. Furthermore, the antimicrobial assay of the synthesized Ag 2 O NPs was carried out by the disc diffusion method against Gram‐positive and Gram‐negative microbial strains.
