Abstract

Four kinds of PbO2electrodes were prepared by electrochemical deposition and three of them were doped by Fe, Ni and Ag, respectively. The characters of the electrodes were analyzed by SEM, XRD, accelerated life tests, and linear scanning voltammetry. The results show that the electrode surfaces are covered by quadrangular β-PbO2crystals. The average grain sizes of the undoped PbO2electrode and Ni-doped PbO2electrode are similar and smaller than that of the Fe-doped PbO2and Ag-doped PbO2electrodes. The Fe-doped PbO2electrode has the longest accelerated test life due to its dense surface. The LSV tests show that the Ni-doped PbO2electrode possesses the highest oxygen evolution potential. From the phenol electrolysis, the Ni-doped PbO2electrode demonstrated the best performance in COD removal efficiency, average current efficiency, and energy consumption.
