利用Pb(Ⅱ)盐与NaOH在室温下进行固相反应制备了纳米级a-PbO粉体(桔红色).借助X射线衍射、透射电镜测试对合成的纳米粉体试样的物理性质作了表征.初步探讨了反应机理.将合成的试样用于改性MnO2电极.1次深度放电测试结果表明，样品的掺杂量在1.25％～5.00％之间对MnO2有良好的改性效果，中等负荷放电时，纳米PbO改性的MnO2电极的放电容量比常粒径PbO改性的MnO2电极的放电容量高出20％以上，比纯国际1#电解锰样(γ-MnO2)的放电容量平均高出约50％，在重负荷放电时，改性MnO2电极的放电容量提高幅度更大.
Nanosize α-PbO particles were prepared by one-step solid state reaction of Pb (Ⅱ) com-pounds with NaOH at room temperature and characterized by XRD and TEM techniques. The forma-tion mechanism of nanophase materials was discussed. The α-PbO modified MnO2 electrodes were fab-ricated and their electrochemical properties were studied by using constant current deep dischargingtests. The results indicate that the optimal portions of α-PbO additives were 1.25～5.00％. Thedischarge capacity of the nanophase α-PbO modified MnO2 electrodes were in average 50％ higher thanthat of International Common Sample No. 1 electrolytic manganese dioxide and 20％ higher than thatof normal α-PbO particle modified MnO2 electrodes in middle load discharging. The most high dis-charge capacity was observed for modified MnO2 electrode at heavy load discharging.
