Abstract:
By studying the electrochemical growth and dissolution of a Ni monolayer on a PdAu bimetallic surface with in situ STM, we demonstrate that Ni grows preferentially on Au(111) in a wide potential range. In contrast, a Ni monolayer covering the entire bimetallic surface can be selectively dissolved from Pd islands. We show that the Ni-substrate interactions play a key role in this selectivity, and we estimate the binding energy of Ni to Pd to be 80 meV smaller than that of Ni to Au.
