Oxygen Evolution Kinetic Parameters of Electrodeposited Composite Inert Electrodes
Pb/WC-ZrO2, Pb/Ag-WC-ZrO2, Pb/WC-ZrO2-CeO2 composite inert electrodes were prepared on aluminum alloy substrate by electrodeposition method from fluorboric bath containing suspension of WC, ZrO2, CeO2 and Ag particles. The stable state polarization curves of oxygen evolution and liner regression curves were obtained. Compared with Pb-1%Ag alloy, the oxygen evolution overpotential of Pb/10.02%WC-3.58%ZrO2, Pb/0.84%Ag-10.01%WC-3.64%ZrO2 and Pb/5.84%WC-2.29%ZrO2-1.32%CeO2 inert electrodes is lower in the range of 12-27mV, the exchange current density is higher two magnitudes above, showing that their catalytic activity of oxygen evolution is better.
