摘要：

The electrolytic deposition industry is currently a chloride and sulfate system, and most of the anodes are titanium-based coatings. However, these anode materials generally have many problems, such as low conductivity and easy failure. Considering the shortcomings of traditional electrodeposition anodes, the preparation of new anode material, PANI pyrolysate doped Ti/SnO2-Sb2O5, and its electrochemical properties of oxygen and chlorine evolution were systematically studied. The OER electrocatalytic activity of PANI pyrolysate doped Ti/SnO2-Sb2O5 (9%) was much lower than that of a traditional Pb-Ag (0.8) alloy anode. And its chlorine-evolution electrocatalytic activity was higher than that of Ti/RuO2 anode and Ti/SnO2-Sb2O5 anode. Under the current density of 500 A/m(2), the chlorine-evolution overpotential of the new electrode was 200 mV lower than that of a traditional electrode Ti/RuO2 anode, and approximately 40 mV lower than that of Ti/SnO2-Sb2O5. Its oxygen evolution potential was 210 mV higher than that of its chlorine evolution potential, making it an ideal anode material for the chloride system.
