摘　　要：本文探讨了基底电极预处理及电沉积条件对ＰｂＯ２电极性能的影响．实验结果表明为了得到结合牢固的ＰｂＯ２沉积层，Ｔｉ电极必须经过化学或电化学刻蚀．电沉积溶液中ＦｅＣｌ３的存在有助于提高ＰｂＯ２电极析氧催化性能和电极稳定性．对上述结果从物质结构和电极过程角度进行了探讨．The effects of pretreatment of substrate electrode and the condition of electrodeposition on the characteristics of PbO2 electrode were investigated in this paper.The experimental results show that Ti electrode shall undergo chemical or electrochemical etching to obtain a welladhered PbO2 doposite layer. The presence of FeCl3 in the electrodeposition solution will increase the catalytic property of PbO2 electrode to oxygen evolution reaction and promote the electrode stability. Above results were disscussed in the view of material structure and electrode process.
