Green synthesis and characterization of fe and ag core-shell bimetallic nanoparticles with the help of Launea procumbens

Core shell bimetallic ferrous and silver bimetallic nanoparticles were synthesized using aqueous leaf extract of Launea procumbens. Initially, Fe nanoparticles were obtained by using plant extract, with FeSO₄ as precursor salt, and thereafter AgNO₃ was added for the formation of shell on it without the help of plant extract. The Fe-Ag NPs thus prepared were characterized by UV visible Spectroscopy, Transmission Electron Microscopy (TEM) and Fourier Transform Infrared (FT-IR) Spectroscopy.
