Abstract：In the non-aqueous solution and recurring to the confocal Raman system, the authors studied the catalysis and oxidation of formic acid on the surface of platinum electrode utilizing surface-enhanced Raman spectroscopy (SERS). Results showed that the intermediate CO, the oxidized product of HCOOH, was produced first. As the potential moves to positive, the first oxidation wave for CO is observed over 0.1 V. As a result the product of CO counteracts its consumeption, so the Raman intensity and coupling under the certain overlay was not decreased. As the oxidation of CO was expedited, the finally oxidized product CO2 was detected at 0.6 V.
