| Abstract: | Carbon monoxide has been adsorbed at controlled potential on a Pt(1 1 1) electrode, which was pre-covered with cyanide up to saturation. From the results obtained, it has been deduced that CO occupies platinum sites between CN molecules with no distortion of the pre-adsorbed cyanide layer. The anodic stripping of CO does not induce modifications of the CN adlayer either. These observations allow the estimation of θCO rather accurately by means of the coulometric method. |
