- Abstract
Plant-mediated synthesis of nanoparticles (NPs) is an efficient and safe alternative to the conventional synthetic route. In this study, silver and gold NPs (AgNPs and AuNPs, respectively) were synthesized via a green route using Ficus sycomorus extract. Tuning the experimental parameters (namely, extract quantity, metal ion concentration, and pH value) allowed control over the size, shape, and size distribution of the NPs. UV-visible spectroscopy has been utilized to monitor the spectral profile changes of the surface plasmon resonance of the NPs under various conditions. The successful preparation of monodispersed spherical AgNPs (4 nm) and AuNPs (11 nm) was confirmed by transmission electron microscopic analysis. Fourier transform infrared spectroscopic data indicated that flavonoid glycosides played a major role in the reduction and stabilization of metal ions. The as-prepared AgNPs and AuNPs were then used as green catalysts for efficient degradation of methylene blue in the presence of sodium borohydride.
