Abstract
On the Pt–PAN–GC and PAN–Pt electrodes in H2SO4solutions that are first saturated with CO and then rid of it, during anodic scans of E r, oxidation peaks are observed at 0.85–0.95 V, which disappear only after repeatedly cycling E rin the interval 0.65 to 1.1 V. The effect is attributed to the capability of a PAN film to sorb considerable CO amounts. The sorption interaction is of a chemical nature. The electrooxidation of CO in the film is closely related to the PAN oxidation, which results in its destruction.
