Figure 5: Ex situ characterization of Ag–Pd nanocages formed during in situ TEM observations.

(a–c) High-resolution HAADF–STEM images of representative porous Ag–Pd nanocages; scale bar, 20 nm. Note the arrays of small nanoparticles in the vicinity of the larger nanocages (outlined by a dashed oval). (d) EDS spectrum from a Ag–Pd nanocage.
