Capturing electrochemical transformations by tip-enhanced Raman spectroscopy

Through the characterization of functional nanomaterials or of molecular architectures under operating conditions (in situ, operando), new insights in their working mechanism will be accessible. In this context, tip-enhanced Raman spectroscopy (TERS) which enables the extraction of precise chemical signatures at the nanoscale represents a great alternative to ultra-high vacuum analytical techniques. This review compiles the recent advances in in situ TERS characterizations and focuses on the strong potential of TERS to characterize the electrochemical processes taking place at the electrode/electrolyte interface.
