Abstract:

In situ FTIR spectroscopy is employed to study the adsorption of cyanide ion CN- sub ads within the double-layer region on a polycrystalline palladium surface in aqueous perchlorate 0.10M NaclO4 electrolyte. Four surface infrared bands in the 1800 to 2200cm range are observed. Surface bands with peak maxima seen at about 2060 and 1980cm-1 are assigned to linear and brigade-bound CN ads, respectively. Cn- sub ads suggest the predominance of the brigade-bound adsorbate on palladium.
