摘要
In order to clarify the time evolution of underpotential deposition (UPD), time-resolved surface X-ray scattering combined with chronoamperometric measurements were carried out on Cu UPD on Pt(111) in the presence of Cl-. Measurements were performed at the X20A beamline. A thin polypropylene film covered the sample and contained the solution in a thin layer configuration. The results show that the electrochemical deposition/stripping processes are far more rapid than the time required to form an ordered CuCl overlayer.
