| 摘 要： | 本文用三角波动电位扫描法对活性炭表面电化学性质进行了探讨.测得活性炭表面基团的浓度为3.4×1~(-7)(moles/em~2),表面基团数为1.08×1~(20),接近文献值.确定表面电活性基团的氧化与还原都是不可逆的.证实H_2O_2产生于O_2与氢醌基的相互作用,结果还支持醌-氢醌活性基团浓度比决定碳电极电位的假设.

| Abstract: | The surface electrochemical properties of the activated carbon have been inves-tated through triangular potentiodynamic sweep method. It has been shown that both the oxidation and reduction of the electroactive surface groups are all irrer-sible in nature. It has also been demonstrated that H2O2 is formed through the mutualinteractions between the O2 molecules and the surface hydroquinone groups. The results also support the hypothesis that the rest potential of a carbon electrode were determined by the ratio of surface concentrations of the electroactive quinone group to hydroquinone group. |
