(a) XRD patterns of the initial Ag sponges and typical Ag-Au-Pd networks (the characteristic peaks of bulk Ag and Pd are provided for comparison). FESEM images showing the Ag sponge (b) before and (c) after GRR; insets show corresponding TEM images and SAED pattern; (d) local magnification of the ligament’s edge, and (e) HRTEM image of a tri-metallic interface.
