Recent Advancements of Electrochemical Attenuated Total Reflection Surface-enhanced Infrared Absorption Spectroscopy

Electrochemical attenuated total reflection surface-enhanced infrared absorption spectroscopy (EC-ATR-SEIRAS) is a powerful analytical tool to obtain molecular-level structural information at the electrode-electrolyte interface towards a better mechanistic understanding of electrochemical processes. In this minireview, we highlight latest research progress of EC-ATR-SEIRAS over the past two years, in terms of technical innovations in IR elements, flow cells, detection sensitivity and time-resolution as well as selected applications in studying electrocatalysis, biosensing and electroplating. Coupling EC-ATR-SEIRAS with other spectroelectrochemical methods is also discussed. And our perspectives on developing EC-ATR-SEIRAS in the near future are put forward in the end.
