Preparation and Electrochemical Properties of the CF-Ti/β-PbO₂ Composite Anode for Zinc Electrowinning

Abstract

This study focused on creating a unique CF-Ti/β-PbO2 composite anode through the combination of powder metallurgy and electrodeposition techniques. A study was conducted on how carbon fiber affects the properties of the anode in the process of zinc electrowinning. The addition of carbon fiber was discovered to enhance the performance of the electrode. When 3% carbon fiber is added, the cell voltage of the composite anode is reduced by 3.06 V, and the current efficiency is increased by 10.16% to 96.39%. Compared to the composite anode without carbon fiber, the corrosion rate of the composite anode containing carbon fiber is decreased by 67.35%. Moreover, the energy usage is reduced by 50%, leading to a potential conservation of 3313.87 kW·h per ton.
