| Outline of Final Research Achievements |
In this study, I aimed for the development of highly efficient photoelectric conversion systems and high performance photocatalysts based on inexpensive Cu nanostructures for the practical application of plasmonic light energy conversion systems utilizing the particular optical phenomenon of metal nanomaterials (localized surface plasmon resonance: LSPR). It was found that the photoelectric conversion systems consisting of the hybrids of porphyrin monolayers as a photoabsorbing layer and plamsonic Cu arrayed structures generated 59 times larger photocurrent signal, as compared with the non-plasmonic photoelectric conversion system based on the planar Cu electrode. On the other hand, Cu2O/Cu plasmonic photocatalysts, which were prepared by oxidizing the Cu arrayed structures, exhibited effective photocatalytic activity by irradiating them with visible/near-infrared light. In addition, the decomposition rate was 84 times faster than that of non-plasmonic Cu2O/Cu photocatalyst.
