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 the 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 ECATR-SEIRAS with other spectroelectrochemical methods is also discussed. And our perspectives on developing EC-ATRSEIRAS in the near future are put forward in the end.
