Voltammetric study of carbon monoxide and carbon dioxide adsorption on smooth and platinized platinum electrodes

The adsorption of carbon monoxide and carbon dioxide on platinized and smooth platinum electrodes has been studied by the potentiodynamic technique. It is shown that the main product of CO and CO/sub 2/ adsorption in the presence H/sub ad/ on the Pt surface is similar, probably the COOH/sub ad/ radical. It has been found that there are some differences between Co and CO/sub 2/ adsorption products on Pt/Pt and smooth platinum electrodes. 75 references, 4 figures, 1 table.
