应用阳极电沉积法制备钛基二氧化锰(Ti/MnO2)电极. 采用X射线衍射(XRD)、扫描电子显微镜(SEM)及能谱（EDS）表征电极结构形貌. 用V~logi及苯酚降解实验优化电极制备工艺参数：在电流密度4 mA•cm-2、Mn2+离子浓度0.5 mol•L-1及温度70 ℃条件下阳极电沉积Ti/MnO2电极. 以苯酚为目标有机物，评价该电极电催化氧化性能，降解7h降解效率达49.6%.Ti-base manganese dioxide (Ti/MnO2) electrode was prepared by anodically electrodeposition technology in this paper. The structure of the electrode, the microstructure of the electrode surface and the element composition of the electrode were analyzed by XRD, SEM and EDS. The preparation process parameters of the electrode were studied in detail with the help of the V~logi curve and phenol degradation curve. The Ti/MnO2 electrode was anodically electrodeposited at current density 4mA•cm-2, the Mn2 + ions concentration 0.5mol•L-1 and temperature70℃. The V~logi curve and phenol degradation curve were used to evaluate electrocatalytic oxidization properties of the electrode with phenol as the goal organisms, achievng 49.6 % degradation efficiency for 7 hours.
