摘要: In this work and for the first time, bimetallic Ag–Pd nanoparticles equipped with a core–shell structure were prepared biologically by employing galvanic displacement reaction in which added PdCl2 reacts an Ag nanotemplate containing adsorbed soaproot (Acanthe phylum bracteatum) extract. Four samples different Ag/Pd molar ratios of 100:2, 100:5, 100:10 100:15 to synthesize structure. The characterized using UV–visible spectroscopy (UV–Vis), X-ray diffraction (XRD), scanning electron microscopy energy-dispersive (SEM–EDX), transmission (TEM) Fourier transform infrared (FTIR) analysis. results from UV–Vis revealed optimal ratio Ag/Pd, is appropriate prepare FTIR XRD confirmed pure formation. images TEM depicted spherical uniformly shaped without any agglomeration particle size 15 nm.
