Abstract
Nanoscale Pt/RuO2 colloid with carbon paste support was synthesized and used to prepare a modified electrode for phenol detection. The results showed that the Pt/RuO2 catalyst has high activity for electrooxidation of phenol with reduced intermediate polymerization due to its significantly low potential for phenol oxidation. The detection limit was as low as 10−9 mol L−1 for the polishable Pt/RuO2/C paste electrode with good reproducibility.
