| Abstract: | The Ti-base manganese dioxide(Ti/MnO2) electrode was prepared by anodic electrodeposition technology.The structure morphology and element composition of the electrode were analyzed by XRD,SEM and EDS.The preparation process parameters of the electrode were studied in detail by the measurements of polarization curves and phenol degradation curves.The Ti/MnO2 electrode was anodically electrodeposited at 4 mA·cm-2,the Mn2+ ions concentration of 0.5 mol·L-1 and 70 ℃.The degradation efficiency of 49.6% for 7 h were achieved with the electrode using phenol as the goal organisms. |
