Abstract

In this work, rotating disk electrodes (RDEs) and surface-enhanced Raman spectroscopy (SERS) have been integrated and used to reveal the mechanism of electrochemical reduction of 4-nitrothiophenol. The electrochemistry of 4-nitrothiophenol was studied in situ on Au@Ag nanoparticles at different potentials using SERS. These spectra together with the RDE results clearly reveal the reduction mechanism of 4-nitrothiophenol to 4-aminothiophenol. This in situ technique offers a new approach in modern electrochemistry that can be used to clarify the reaction mechanisms of different nitrobenzenes at a molecular level.
