Voltammetric and kinetic results are described for the electrocatalytic oxidations of various compounds at doped‐ film electrodes on Ti substrates. Compounds tested include dimethyl sulfoxide and several thiophene derivatives. Results are emphasized for films doped with FeIII , and with AgI and BiV , that were electrolytically deposited on Ti substrates with the presence of an interlayer of deposited from acidic solutions of Pb2+ and. These "laminar" film electrodes are quite stable and offer significantly improved catalytic activity for various anodic oxygen‐transfer reactions in comparison to pure electrodes.
