Titel:
In-situ characterization of metal/electrolyte interfaces: sulfate adsorption on Cu(111) 
Abstract:
As a prototypical example of a metal-electrolyte interface the adsorption of sulfate on well defined Cu(111) single crystal electrodes from a 5mM H2SO4 soln. was studied by in-situ electrochem. scanning tunneling microscopy (EC-STM) and IR reflection absorption spectroscopy (IRAS). The EC-STM images show the formation of the known Moire-like structure upon adsorption of sulfate on the Cu(111) surface. While IR frequency data fail to provide information about the anion adsorption site, high-resol...    »
