| Outline of Final Research Achievements |
Highly active electrocatalysts such as platinum (Pt) and palladium (Pd) have poor plasmonic activity, resulting in the difficulty to probe electrochemical reactions by surface enhanced Raman scattering (SERS) spectroscopy. In this study, we have achieved in situ SERS measurements of adsorbed molecules at Pt electrode surfaces by excitation of long range surface plasmon (LRSP) and surface plasmon standing wave coupled with "whispering gallery" modes induced in plasmonic crystalline structures. We have established evaluation platform to develop more active electrocatalysts based on surface vibrational spectroscopy.
