Abstract:
An ultralow amount of platinum can be deposited on the gold surface using copper underpotential deposition and galvanic exchange. The platinum tended to deposit as layers on the octahedral gold nanocrystals with an Au(111) surface, while it aggregated and formed small particles on the cubic gold nanocrystals with an Au(100) surface.
