Abstract:

Green chemistry techniques are increasingly used to produce nanomaterials from easily accessible natural resources. The present study utilized a cost-effective and environmentally sustainable method to separately synthesize copper oxide, iron oxide, and mixed oxide nanoparticles,   with the help of fruit peel extracts. The nano-oxides were synthesized from the local fruit peels, specifically orange, cherry, and sidra (Ziziphus jujuba). The findings from scanning electron microscopy (SEM) and particle size analysis (PSA) revealed that the nanoparticles are semi-spherical, with particle sizes ranging from 83.9 to 118.7 nm for CuO, from 95.2 to 119.8 nm for Fe2O3, and from 60.6 to 90.4 nm for mixed oxides extracted from three fruit peels. The conducted experiments on bacterial and fungal resistance revealed that the produced oxides are effective antibacterial and antifungal particles. The synthesized nanoparticles were also analyzed through AFM and Toxicity.
