Abstract:

Considering the study of electrochemical surface adsorption and reaction processes at the molecular level, Surface-enhanced Raman spectroscopy(SERS) shows its particular merits and provides a powerful technical method for this study. However, the mechanism of enhancement needs to be further explored. This review summarizes the systematic work on electrochemical SERS(EC-SERS) by combining quantum chemistry calculations. On the basis of these studies, we can make deep insight for extracting the physical and chemical information in EC-SERS spectra. Focusing on adsorption of pyridine on the electrochemical surface, adsorption and reactional process of water on the surface, and surface coupling reaction for p-aminothiophenol, we had illustrated the nature of the adsorption and photochemical reactions on the electrochemical surface.
