| Outline of Final Research Achievements |
In this study, the plasmon-induced water oxidation process was investigated via a in-situ SERS measurement. The interfacial structure effect on the charge separation was determined at the atomic layer scale. A tight contact between the metal nanoparticles and its support metal oxide is highly demanded for efficient plasmon-induced charge separation. Based on the understanding of the plasmon-induced water oxidation process and the interfacial structure effect on the charge separation, we successfully constructed a novel plasmonic structure, which shows strong light absorption, for broadband plasmon-enhanced solar energy conversion.
