The origin and significance of the anodic prepeak (peak A0), seen in cyclic voltammetric studies of hydrous Ir oxide films in acidic solution just prior to the large Ir(III)/(IV) redox peaks (A1/C1), has been examined in this work. By also studying only very thin films, a corresponding cathodic feature (peak C0) has also been identified. The pH dependence of the A0/C0 peaks, assumed to also depict the Ir(III)/(IV) process, has been examined in sulfuric acid solutions, indicating that a ca. −80… CONTINUE READING
