Abstract

The structure of Au-Pd bimetallic nanoparticles prepared by sonochemical technique was investigated by an analytical transmission electron microscopy. The core (Au)-shell (Pd) structure was clearly confirmed by the intensity profile of annular dark field scanning transmission electron microscopy (ADF-STEM). The line-scan analysis of energy dispersive X-ray spectroscopy (EDS) in STEM mode also revealed the Au core-Pd shell structure. The selected area electron diffraction pattern from the Au-Pd nanoparticles indicated the possibility that the crystal lattice of Pd shell is expanded and coincident with the crystal lattice of Au core.
