- Abstract:
- Sulfate adlayers on a Cu(111) electrode were investigated by in-situ IR reflection absorption spectroscopy (IRRAS) combined with in-situ STM. The latter data show clear evidence for a bridging bidentate coordination of sulfate to the Cu surface. The IR spectra exhibit one single absorption band in the frequency range of 1205-1225 cm-1. Further anal. of the band frequency and intensity with respect to the electrode potential leads to sulfate desorption with sulfate remaining in islands at the sur... »
