Abstract

We demonstrate highly efficient electocatalytic activities of single crystalline RuO ₂ nanorods grown on carbon fiber (CF), i.e., RuO ₂ nanorod-CF hybrid microelectrode, prepared by a simple thermal annealing process from the Ru(OH) ₃ precursor at 300 °C. The general electrochemical activity of a RuO ₂ nanorod-CF microelectrode represents faster electron transfer for the [Fe(CN) ₆] ^3-/4- couple than that of the bare CF microelectrode which are confirmed from the cyclic voltammetry (CV) measurement. Also, the amperometric response for the H ₂O ₂ oxidation is remarkably facilitated at the RuO ₂ nanorod-CF microelectrode by not only the enlarged surface area but the high electrocatalytic activity of the RuO ₂ nanorod material itself. Furthermore, a single microelectrode of RuO ₂ nanorod-CF exhibits the superior tolerance to Cl ^- ion poisoning unlike Pt-based electrocatalysts, indicating the promising sensor candidate in physiological conditions.
