摘　　要：锌电沉积生产中,传统铅阳极因成本低、导电性好、易加工等优点而被广泛应用,但铅阳极在电解过程中的腐蚀也导致锌产物污染、电解液污染及阳极损耗等问题。提高阳极的电化学活性及耐蚀稳定性成为锌电沉积工艺的重要研究方向之一。近年来,学者们基于铅阳极的耐腐蚀机制,研发了多种电化学性能优异的耐腐蚀阳极,包括铅合金阳极、复合PbO2阳极和过渡金属氧化物涂层阳极等。本文综述了铅阳极、铅合金阳极、PbO2阳极和过渡金属氧化物涂层阳极等锌电沉积阳极的研究进展,对锌电沉积阳极的发展方向进行了展望。Traditional lead anodes are widely used in production of zinc by electrowinning due to their low cost,good conductivity and easy processing. However, the corrosion of lead anodes during the electrolytic process has also lead to the pollution of zinc products and electrolyte and increase of anode use costs. Improving the electrochemical activity and corrosion resistance of the anodes has become one of the important research directions of zinc electrowinning technology. In recent years, based on the corrosion-resistant mechanism in zinc electrowinning processes, a variety of corrosion-resistant anodes with excellent electrochemical performance have been developed, including lead alloy, PbO2, and transition metal oxide coated anodes. This article reviews the research progress of zinc electrowinning anodes such as lead alloy, PbO2 and transition metal oxide coated anodes, and give a prospect of their future development.
