The Redox Chemistry of Ruthenium Dioxide: A Cyclic Voltammetry Study—Review and Revision

Figure 10

Apparent diffusion coefficients at different scan rates according to Randles-Sevčik equation for a RuO₂/Ti electrode in 1-molar H₂SO₄ at 25°C assuming one-electron transfer () and unit surface area (1 cm²) for reason of comparability. Fit quality: Ru-H ( = 0.9511, >0.3 V/s); Ru(III)/(IV) ( = 0.9952); Ru(IV)/(V) ( = 0.9995); Ru(V)/(VIII) ( = 0.997; 0.1–1 V/s) and ( = 0.991; >1 V/s).
