Abstract:

The synergy between two different metals provides a dramatic enhancement in the bimetallic nanoparticles’ catalytic properties since bimetallization improves the properties associated with the presence of two individual metals. Therefore, herein, we reported the facile, one-pot phytosynthesis of Ag/Fe bimetallic nanoparticles via reduction process using phytochemicals present in the Maclura pumifera leaf aqueous extract. During the Phyto assisted nanofabrication of Ag/Fe nanoparticles, the reduction of Ag+ and Fe۲+ metal ions to Ag/Fe NPs takes place according to their reduction potential. The UV-Vis spectroscopic technique was initially used for the Ag/Fe nanoparticle formation in which the absorption band at ۴۳۱ nm were observed for Ag/Fe nanoparticles, respectively. Transmission electron microscopy (TEM) analysis were used to investigate the size and shape of phytosynthesized Ag/Fe nanoparticles, and it was revealed that the as-synthesized Ag/Fe nanoparticles are nearly spherical with an average size of ۳۰-۵۰ nm. Fourier transform infrared spectroscopy (FT-IR) analysis was performed to confirm the role of reducing and capping/stabilizing agents in the synthesis of Ag/Fe bimetallic nanoparticles. These results suggest that such stable and uniform Ag/Fe bimetallic nanoparticles can be synthesized rapidly and simply and pH had impressive effect to phytosythesis of bimetallic nanoparticles.
