An Infrared Spectroelectrochemical Study of Cyanide Adsorption on Palladium Surfaces

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 2200/cm 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.
