摘要

通过高扫描速率的循环伏安法,详细研究了RuO2在酸性和碱性溶液中的电化学性质。在硫酸和氢氧化钠中可以区分出13个电流峰。关于RuO2电极的pH敏感性,我们考虑了电荷计算、峰值电流和表观扩散系数。Ru(I)−Ru(III)物种阐明了Ru(II)氧化的性质。

The Redox Chemistry of Ruthenium Dioxide: A Cyclic Voltammetry Study—Review and Revision
By cyclic voltammetry at high scan rates, the electrochemical properties of RuO2 in acidic and alkaline solutions were investigated in detail. Thirteen current peaks can be distinguished in sulfuric acid and sodium hydroxide. With respect to the pH sensitivity of RuO2 electrodes, we considered charge calculations, peak currents, and apparent diffusion coefficients. The nature of the Ru(II) oxidation was clarified by Ru(I)−Ru(III) species.
