The operando investigation of electrochemical interfaces plays an important role in advancing our understanding of electrochemical processes at the molecular level. This research focuses on elucidating the interactions and dynamics occurring within these interfaces during electrocatalysis and electrodeposition processes (e.g., CO2 reduction, Cu deposition). By integrating advanced techniques such as electrochemical mass spectrometry and vibrational spectroscopies, such as shell isolated nanoparticle enhanced Raman spectroscopy, we aim to interrogate the microenvironments and mechanistic details of chemical transformations at the electrode-electrolyte interface in real-time and under operating conditions. This approach not only provides insights into reaction mechanisms but also enables the optimization of electrode materials and electrolytes for enhanced performance in electrochemical applications. The findings from this study are expected to launch cutting edge metrologies to new levels and contribute significantly to the development of next-generation electrochemical technologies.
