Description

technical field [0001] The invention relates to a spectroscopic electrolytic cell, in particular to a spectroscopic electrolytic cell suitable for Raman spectrum in-situ characterization. Background technique [0002] The traditional electrochemical method mainly measures the electrode potential or current, and obtains the macroscopic average information of the electrode interface. It is difficult to provide the behavior of molecules at the surface interface from the molecular structure level. Applying molecular spectroscopic techniques such as ultraviolet, infrared, and Raman to the field research of electrochemistry can directly obtain information about the interaction mode, adsorption orientation, and coverage of species on the electrode surface at the molecular level. [0003] Raman spectroscopy, especially surface-enhanced Raman spectroscopy, has unique advantages such as little interference from water and high surface sensitivity, and has been used in the study of elec...
