Abstract

In this study, Ag-CuO bimetallic nanoparticles were synthesized from Citrus limetta peel extract. Synthesized Ag-CuO nanoparticles were characterized by UV–Visible spectroscopy, FE-SEM, EDS, XRD, and zeta potential analysis. UV–Vis spectrum demonstrated surface plasmon resonance peaks at 340 nm and 282 nm for silver and copper oxide nanoparticles, respectively. FE-SEM micrography indicated a non-spherical, irregular morphology with uniform distribution and apparent surface roughness, and EDS showed the elemental ratio with 97.93% Ag and 2.07% Cu. Synthesized nanoparticles showed potential catalytic performance towards the degradation of Congo red (CR) with NaBH₄ up to 85%. In summary, Citrus limetta peel mediated Ag-CuO nanoparticles provide a green, economically feasible, and scalable platform for environmental remediation and antibacterial applications.
