Catalysis is a fundamental process in many industrial and environmental applications, involving complex reactions often taking place on surfaces and interfaces. Understanding the mechanisms at the nanoscale is crucial. TERS provides several advantages in this context: - High Spatial Resolution: TERS can achieve spatial resolutions down to the nanometer scale, allowing scientists to study catalytic processes at the level of individual nanoparticles or molecular sites. - Chemical Sensitivity: The technique offers enhanced sensitivity, making it possible to detect and identify reaction intermediates and products that are present in very low concentrations. - In Situ and Operando Studies: TERS can be employed under realistic reaction conditions, enabling the observation of catalytic processes as they happen.
