Heterogeneous rate constants for the anodic oxidation of many inorganic and organic compounds at electrolytically deposited beta-PbO{sub 2} film electrodes in 1.0M HClO{sub 4} are increased by doping the oxide with Bi(III). The rate constants at the mixed-oxide electrode rise sharply for a change from 0 to 10 mole percent (m/o) Bi(III) in the electrodeposition solution, and reach a mass transport-limited value for some compounds at 40 m/o Bi(III). Results of kinetic, voltammetric, and spectroscopic studies of these electrodes are described. In addition, the lifetime of Bi(III)-doped PbO{sub 2} film electrodes is discussed as a function of concentration, rotation speed, analyte, and applied voltage.
