本文用气体电量计法分解极化曲线研究了光滑铂电极上Ｏ２和Ｃ２Ｏ６２－离子的阳极形成动力学。实验结果表明：Ｏ２和Ｃ２Ｏ６２－的阳极极化曲线的Ｔａｆｅｌ斜率接近于２．３０３ＲＴ／βＦ（β≈０．４１～０．６４）。Ｏ２和Ｃ２Ｏ６２－形成反应相对于ＣＯ３２－的反应级数分别介于１．０９～１．４７和１．０６～１．９。它们的表现反应级数随电极电位增加而降低。证明在铂电极上Ｏ２和Ｃ２Ｏ６２－的阳极形成均是通过ＣＯ３２－的直接放电。
In this paper, the anode formation kinetics of O2 and C2O62- ions on a smooth platinum electrode was investigated by decomposing the polarization curves with a gas-gas meter. The experimental results show that the Tafel slope of anodic polarization curves of O2 and C2O62- is close to 2.303RT / βF (β≈0.41 ~ 0.64). The reaction order of O2 and C2O62-formation reaction with respect to CO32- is 1.09-1.47 and 1.06-1.9, respectively. Their performance response series decreases with increasing electrode potential. It is demonstrated that the anode formation of O2 and C2O62- on the platinum electrode are all direct discharges through CO32-.
