Voltammetric and kinetic results are described for the electrocatalytic oxidations of various compounds at doped PbO 2 ‐ film electrodes on Ti substrates. Compounds tested include dimethyl sulfoxide and several thiophene derivatives. Results are emphasized for PbO 2 films doped with Fe III ( Fe ‐ PbO 2 ) , and with Ag I and Bi V ( Ag ‐ Bi ‐ PbO 2 ) , that were electrolytically deposited on Ti substrates with the presence of an interlayer of PbO 2 deposited from acidic solutions of Pb 2+ and NaF . These “laminar” film electrodes are quite stable and offer significantly improved catalytic activity for various anodic oxygen‐transfer reactions in comparison to pure PbO 2 ‐ film electrodes.
