中文摘要：

采用旋转圆盘电极（Rotating disk electrode,RDE）,通过循环伏安法（Cyclic voltammetry,CV）分析了硝酸锰浓度、硝酸浓度、硝酸铅浓度和溶液温度对PbO_2和MnO_2共沉积的影响规律,获得了PbO_2和MnO_2共沉积的最优条件。探究了旋转圆盘电极转速对PbO_2和MnO_2共沉积的影响,发现最优条件下其共沉积行为主要受电化学控制。使用扫描电镜（Scanning electron microscope,SEM）观察PbO_2-MnO_2沉积层表面形貌,发现PbO_2-MnO_2沉积层表面以圆球状结构为主。通过X射线衍射仪（X-ray diffraction,XRD）检测到PbO_2-MnO_2沉积层表面出现了一种α-MnO_2、α-PbO_2、β-PbO_2三相同时存在的混合结晶状态。

英文摘要：

The influences of concentration of Mn（NO_3）_2,HNO_3,Pb（NO_3）_2and solution temperature on PbO_2-MnO_2co-deposition were studied by cyclic voltammetry using rotating disk electrode,and the theoretical optimum conditions of the PbO_2 and MnO_2co-deposition were obtained.The experiments concerning the effects of rotation rate of the electrode on the co-deposition process of PbO_2 and MnO_2indicate that the behavior of PbO_2 and MnO_2co-deposition process is mainly determined by the electrochemical process.Scanning electron microscopy（SEM）was applied to observe the surface morphology of PbO_2-MnO_2 layer and the results confirmed the spherical structure of the PbO_2-MnO_2 layer.Besides,a ternary-phase-mixed crystal phase ofα-MnO_2,α-PbO_2andβ-PbO_2 in the PbO_2-MnO_2 layer was detected by X-ray diffraction（XRD）technology.
