摘　　要：在硝酸铅镀液中添加Mn(NO3)2,直流电沉积方法制备不锈钢基β-PbO2电极.利用SEM、EDS表征电极的形貌和Mn含量,阳极极化曲线和动力学参数表征电极的电催化活性.结果表明:Mn(NO3)2的添加量为6g/L时,表面形貌为颗粒状,排列紧凑,其电催化活性最好.掺杂Mn2+制备的不锈钢基β-PbO2电极与Pb-(1%)Ag合金阳极相比,槽电压降低,电流效率提高.β-PbO2 electrode on stainless steel were prepared in Pb（NO3 ）2 plating solution adding Mn（NO3 ）2 by DC deposition. SEM, XRD and linear sweep vohammetry（LSV） were used for the analysis of the surface structure, phase composition and the catalytic activity of oxygen evolution potential analysis. The results show that as the concentration of addition Mn （NO3）2 was 6 g / L, the surface morphology was granular, compact arrangement and the electro-catalytic activity was the best. Compared with Pb-（1%）Ag alloy anode, this electrode has the advantages of lower cell potential and higher current efficiency.
