Figure 1: Galvanic replacement of Ag particles in Pd-salt solution without electron irradiation.

From: In situ liquid-cell electron microscopy of silver–palladium galvanic replacement reactions on silver nanoparticles

Figure 1

(a) TEM image of the initial Ag nanoparticles; scale bar, 50 nm. (b) HR-TEM images of three representative Ag nanoparticles; scale bar, 20 nm. (c) TEM image of the Ag–Pd hollow nanostructures formed after 4 h of immersion of the Ag nanoparticles in 50 μM PdCl2 aqueous solution. For ease of comparison, the image scale is identical to that in a; scale bar, 50 nm. (d,e) EDS spectra of a Ag nanoparticle and a Ag–Pd hollow-shell nanostructure, respectively.
