| Abstract: | The electrooxidation behavior of piperonal (PI) and isosafrole (ISF) on roughened platinum in non-aqueous system was investigated by cyclic voltammogram (CV) and in-situ surface enhanced raman scattering (SERS) spectroscopy. On the one hand, PI would be oxidated to piperic acid if the potential was equal to 1.50 V or higher than 1.50 V. On the other hand, the in- situ SERS results demonatrated that the exciting laser of 632.8 nm promoted the electrooxidation of PI at the oxidation potential (≥1.50 V). As a result, the potential, which was used to directly oxidate ISF to PI should be controlled between 1.20 V and 1.50 V. |
