摘要： 本文用稳态法测定了塔费尔斜率、OH-离子的表观反应级数和表观活化能,着重分析了线性电位扫描图及该反应的暂态特性。提出了在该电极上氧气析出反应的初步机理。

Abstract: The oxygen evolution reaction on NiCO2O4 and Nd0.8 Sr0.2 CoO3 have been investigated. Tafel slopes, apparent reaction orders of OH- and apparent activation energies are determined by the steady-state method. Analysis of the transient characteristics of the linear potential swept diagrams is being emphasized. Summing up both the steady-state and transient characteristics, a preliminary mechanism of oxygen evolution reaction on these electrodes is propounded. Computer modeling calculations of this mechanism have been carried out. The results obtained are in fair agreement with the experimental curves.
