Abstract
Ti/PbO2–TiO2–Ce(NO3)4 electrode for zinc electrowinning was prepared, and the effect of Ce(NO3)4 content on the electrochemical properties of zinc electrowinning anode was studied. Morphology and composition of the Ti/PbO2 electrode before and after polarization were analyzed by SEM and XRD. The corrosion mechanism was investigated by linear sweep voltammetry (LSV), cyclic voltammetry (CV) ,and electrochemical impedance spectroscopy (EIS) analyses. The cell voltage, current efficiency, corrosion rate, anode lifetime, and failure mechanism of Ti/PbO2 and Ti/PbO2–TiO2–Ce(NO3)4 were analyzed by simulating zinc electrowinning experiments. It was found that Ce(NO3)4 promoted the oxygen evolution reaction, and reduced the oxygen evolution potential and energy consumption. The analysis of oxygen evolution peak and reduction peak shows that Ti/PbO2–TiO2–Ce(NO3)4 electrode has good invertibility. In addition, it was found that the addition of Ce(NO3)4 increased the activity of the coating, and Ti/PbO2–TiO2–Ce(NO3)4 (0.5 g L−1) had the best activity. Compared with Ti/PbO2, the cell voltage of Ti/PbO2–TiO2–Ce(NO3)4 (0.5 g L−1) was reduced by 0.15 V, the current efficiency was improved by 4.3%, the corrosion rate was reduced by 0.0331 g A−1 h−1, and the lifetime was improved by 5 h.
