Mn^(3+)/Mn^(2+)氧化还原体系的旋转圆盘电极法性能

Studies on the Mn^(3+)/Mn^(2+) redox couple on platinum electrode

The electrochemical behaviors of Mn 3+ /Mn 2+ redox couple used as the cathodic electroactive material in a new electrochemical storing energy system (redox flow cell) were studied by means of RDE techniques on platinum electrode.The experiment results showed that kinetics of electrode process was controlled by mass transported on the static Pteledtrode;and on RDE electron transfer and/or mass transport could become the rate controlling step of the electrode process depending on the magnitude of the overpotential and the rotating speed of RDE.
