This study reports the green synthesis of Fe–Ag–V ternary oxide nanoparticles using gum arabic as a natural reducing and stabilizing agent. The biopolymer’s hydroxyl, carboxyl, and other functional groups promoted nucleation, growth, and stabilization without toxic reagents. Characterization by FTIR, DLS, XRD, and SEM confirmed successful synthesis. FTIR peaks verified gum arabic’s role in reduction and stabilization, while additional signals identified iron, vanadium, and silver oxides. DLS showed an average size of 38.24 nm (PDI 0.636), and XRD revealed a face-centered cubic structure with ~15.6 nm crystallites. SEM indicated rod-like and irregular morphologies, suggesting high surface area. Antibacterial assays showed strong activity, with MICs as low as 0.3125 mg/ml against Staphylococcus aureus, and notable effects on E. coli, K. pneumoniae, and B. cereus. These results demonstrate gum arabic as a sustainable bio-matrix and highlight the biomedical, catalytic, and environmental potential of the ternary oxides. |
