Nanolaminate Nano-Optoelectrodes Enable Dual-Channel Plasmon-Enhanced Raman Spectroscopy for Electrochemistry.

ABSTRACT: In situ monitoring of short-lived transition states (TSs) is crucial for understanding electrochemical reaction mechanisms but remains challenging. Conventional electrochemical surface-enhanced Raman spectroscopy (EC-SERS) primarily provides vibrational information, with limitations in hotspot reproducibility and often overlooking electronic information associated with TSs. This study introduces a dual-channel EC-SERS strategy using nanolaminate nano-optoelectrode (NLNOE) devices, integrating plasmon-enhanced vibrational Raman scattering (PE-VRS) and plasmon-enhanced electronic Raman scattering (PE-ERS) to concurrently probe TS dynamics within electrically connected plasmonic nanocavities. Using the AgCl(s) + e^-⇌Ag(s) + Cl^-(aq) redox system, this approach distinct PE-
