Electrooxidation of Phenol on PtRh and PtRu Alloys in 0.1 M NaOH Solution

摘要

This communication reports on kinetics of phenol electrooxidation reaction (PhER), studied at PtRhand PtRu alloy electrodes in 0.1 M NaOH supporting solution. The kinetics of PhER were analysedbased on potential-dependent, a.c. impedance-derived values of charge-transfer resistance andcapacitance parameters. Finally, obtained results were compared to those recently recorded onpolycrystalline Pt electrode surface under analogous experimental conditions.
