摘要：

Electron exchange reaction rates were compared for boron-doped diamond (BDD), Pt, Au and RuO2 using [Ru(NH3)(6)](3+/2+) as a redox couple. The study was carried out by cyclic voltammetry; calculations were performed by Nicholson's procedure. The results show that the rate constants on BDD, Pt and Au are qualitatively similar, one order of magnitude higher than on RuO2. The outcome is explained in terms of the specific structure of the interface between oxides and electrolyte solutions.
