Electron microscopy characterization of the Au nanoframes prepared by the galvanic replacement reaction between 50 µL of Ag nanocubes and 6 mL of 0.2 mmol / L AuCl2−: (a) SEM image of the Au nanoframes and (b) the same sample tilted by 45°; (c) TEM image of the Au nanoframe; (d) high-resolution TEM image of a corner of the Au nanoframe taken from the region as labeled in the inset. The scale bar in the inset represents 20 nm. The lattice spacing of 2.04 Å can be indexed as the {200} planes of Au. In the FFT pattern (inset), the spots enclosed by the circle and square can be indexed to the {220} and {200} reflections, respectively
