Here, a hollowed-out Au@AgPt core-frame nanostructure is carved in the presence of PtCl62−via galvanic replacement (GR) reaction, during which the dissolution of Ag atoms from the {100} facets and the deposition of Pt atoms on the active edges of the nanocubes occur. Both ex situ and in situ monitoring of the plasmonic and structural evolutions at the single-particle level, confirmed also by theoretical simulations, shows a three-phase mechanism involved.
