Voltammetric peak currents against the square root of scan rate: RuO2/Ti electrode in 1 M NaOH; Insert: peak current versus scan rate. Fit quality for ~ ν (0.1–0.5 V/s): Ru-H ( = 0.9999); possibly Ru(II)/(III) ( = 0.988); Ru(III)/(IV) ( = 0.9998); Ru(IV)/(VI) ( = 0.9991); Ru(VI)/(VII) ( = 1); fit quality for ~ ν1/2 (>1.0 V/s): possibly Ru(II)/(III) ( = 0.9996); Ru(III)/(IV) ( = 0.994); Ru(IV)/(VI) ( = 0.996); Ru(VI)/(VII) ( = 0.939).
