| Popis: | The green method for metal nanoparticles has been gaining more interest owing to its low cost and safe nature. The Carissa edulis (C. edulis) dried fruit extract was utilized for the synthesis silver oxide nanoparticles (Ag2O NPs). The microwave extraction process was optimized using Box-Behnken Design (BBD). The good optimization was found to be 400 W, 70 °C and 30 mL of solvent. We have observed 0.17 g of extract yield from this method. The green synthesized Ag2O NPs were analyzed by various analytical techniques. The absorption peak around 420 nm confirms the formation of Ag2O NPs. Further, the SEM and TEM results showed cube and ellipsoid shape with 1.5–2 nm. The Photocatalytic of Ag2O NPs showed 95.8% of degradation of Congo red with rate constant of 0.0233 min−1 and the antibacterial activity of Ag2O NPs was showed high zone of inhibition (10 mm) against E. coli. Therefore, C. edulis extract mediated Ag2O NPs can be used to carry further research in environmental science and biotechnology. |
