heterodimers (M= Pd, Au, Pt). Sulfide ions can give fine control over the reaction kinetics of
Ag precursors, resulting in the anisotropic overgrowth of Ag to realize the dumbbell-like
heterodimers irrespective of the surface facets or components of the M domain. The M–Ag
heterodimers were facilely transformed to M–Ag2S heterodimers via a simple sulfidation
reaction. This study provides a versatile approach to realizing not only metal–metal …
