The present study investigated the electrodeposition of Pb-0.6%Sb/α-PbO2/β-PbO2-Carbon Nanotube (CNTs) energy-saving electrodes with different proportions co-deposited CNTs and compared application industrial Pb-0.8 wt%Ag anodes in a long-period zinc process. When concentration was 3 g·L-1, charge transfer resistance Rct oxygen-evolution reaction reached minimum value (6.140 Ω·cm2), while corrosion achieved maximum (Ecorr 1.3255 V, Icorr 2.06 × 10-4 A). co-deposition considerably refined grain size enhanced electrocatalytic activity. Additionally, modification mechanism β-PbO2 elucidated. During long period electro-deposition process, Pb-0.6%Sb/α-PbO2/β-PbO2-CNTs reduced cell voltage power consumption by 299 mV 373.97 kWt/(t·Zn) anodes, respectively. overall energy conservation effect remarkable.

The performance of the anode varies from impurity ions in copper electrowinning process. This work focused on variation electrochemical behavior Pb-0.06%Ca-1.2%Sn as Fe (Fe3+ and/or Fe2+) existed electrolyte by characterization. Copper electrodeposition experiments were conducted under a current density 300 A/m2, with ion concentration controlled within range 0 to 20 g/L and Cu maintained at 45 temperature °C. corrosion resistance, catalytic activity, structural composition film layer was analyzed in-depth according presence ions. results show that structure PbO2 surface changed doped into film, oxygen evolution activity also improved. However, resistance decreased increasing Fe3+ concentration. Furthermore, addition 2 Fe2+ containing led an elevation some extent further increased activity.
