Abstract:
Silver nanoparticles (Ag NPs)-reduced graphene oxide was prepared through the in situ nucleation of Ag NPs on reduced, modified GO (rMGO). Glycine was used as a green reducing as well as modifier agent for GO to obtain rMGO. Nucleation of Ag NPs on rMGO was carried out at ۸۰ ◦C at aqueous media. UV-Vis, FT-IR, and XRD techniques confirmed the reduction, modification, and synthesis of Ag NPs. Meanwhile, the morphology of rMGO and rMGO-Ag nanocomposite was investigated with SEM and TEM images. The synthesized nanocomposite showed excellent catalytic behavior for the reduction of ۴-nitrophenol (۴-NP) by NaBH۴. The electrocatalytic behavior of Ag NPs on rMGO for electroreduction of H۲O۲ was investigated by cyclic voltammetry (CV). In the optimum condition, H۲O۲ was determined with a detection limit of ۹.۴ µM and sensitivity of ۰.۵۲ µAµM-۱. In addition, with the investigation of MIC data of nanocomposite, it was distinguished that this compound has excellent antibacterial activity.
