摘要
The cathodic reduction mechanism of MnO2 electrode is studied by means of the rotating ring-disk electrode. The mass transport process in the solution plays an important role in the reduction process of MnO2 electrode. The relation between IR-1 and ω-1/2 is deduced as a diagnostic criterion of the reduction medianism. The dissolutionprecipitation and the electron-proton mechanism occur simultaneously but the relative contributions are qulte different in various pH value solutions.
