AI Insight
This study reports the green synthesis of antimony oxide nanoparticles (Sb2O3 NPs) using an aqueous extract of Actinidia deliciosa (kiwi fruit), which serves as a natural reducing and capping agent. The resulting nanoparticles were incorporated into a chitosan matrix to form a composite material, which was subsequently characterized and evaluated for antibacterial activity against selected bacterial strains and photocatalytic degradation of organic dyes. Results indicated that the chitosan-Sb2O3 composite demonstrated enhanced antibacterial performance and improved photocatalytic efficiency compared to unsupported nanoparticles alone.
Why it matters
Green synthesis routes reduce reliance on hazardous chemical reagents, making nanoparticle production more environmentally sustainable. The composite material has potential applications in water treatment, food packaging, and infection control surfaces.
