(A) Schematic illustrating the major morphological and structural changes involved in the galvanic replacement reaction between a sharp Ag nanocube and HAuCl4. The cross-sectional views correspond to the plane along the dashed lines. (B) SEM image of the sacrificial templates, Ag nanocubes; and (C-G) SEM images for the hollow nanostructures obtained from sequential stages of the galvanic replacement reaction. Insets of (D) and (E) are microtomed TEM samples showing the hollow interior, and insets of (B) and (F) are the electron diffraction patterns for the corresponding nanostructures. The 100 nm scale bar applies to all SEM images. Reproduced with permission from [22], Copyright 2004 American Chemical Society.
