铜电积用铝棒Pb-Sn-Sb/α-PbO2-Co3O4复合电极材料及制备方法
摘要：
铜电积用铝棒Pb-Sn-Sb/α-PbO2-Co3O4复合电极材料及制备方法，所述电极材料包括铝棒基体(1)、复合在铝棒基体表面的Sn-Sb合金镀层(2)、复合在Sn-Sb合金镀层表面引入了纳米CeO2颗粒的Pb-Sn-Sb复合镀层(3)、覆盖于Pb-Sn-Sb复合镀层表面引入了纳米Co3O4颗粒的α-PbO2复合镀层(4)。本发明制备的铜电积用铝棒Pb-Sn-Sb/α-PbO2-Co3O4复合电极材料与传统的铅基多元合金相比，在不改变电解槽结构、电解液组成和操作规范的基础上，导电性显著提高，产生气泡较小，带出的酸雾少，槽电压可降低120mV，材料成本降低20％，电流效率提高2％以上。
摘要（英）：

The invention provides an aluminium bar Pb-Sn-Sb/alpha-PbO2-Co3O4 composite electrode material for copper electrodeposition and a preparation method. The electrode material comprises an aluminium barbasal body (1), a Sn-Sb alloy coating (2), a Pb-Sn-Sb composite coating (3) and an alpha-PbO2 composite coating (4). The Sn-Sb alloy coating (2) is composited on the surface of the aluminium bar basalbody. The Pb-Sn-Sb composite coating (3) is composited on the surface of the Sn-Sb alloy coating and introduced with nanometer CeO2 particles. The alpha-PbO2 composite coating (4) covers the surfaceof the Pb-Sn-Sb composite coating and is introduced with nanometer Co3O4 particles. Compared with traditional lead base multi-element alloy, the electrical conductivity of the preparative aluminium bar Pb-Sn-Sb/alpha-PbO2-Co3O4 composite electrode material is outstandingly increased, bubbles generated are smaller, acid mist carried over is less, cell voltage can be reduced by 120 mV, the cost of material reduced by 20%, and the current efficiency is increased by above 2%, without the basics of changing the cell construction, electrolyte composition and operation specifications.
