| Outline of Final Research Achievements |
To develop the novel photon-energy conversion system with high conversion efficiency from solar energy to chemical energy, Hybridization of porphyrin, which is one of photosensitizer, with semiconductor nanosheet and those photoconversion property was investigated in this study. As results, we could succeeded in preparing the hetero-stacked hybrid film between porphyrins and semicondutor such as cobaltate nanosheet and Rh-doped titanate nanosheet by layer-by-layer method. When porphyrin molecules in these hybrid films were photo-excited by visible light (450 nm), the photo-induced electron transfer reaction from porphyrin through the nanosheet could occur. Moreover, we could observed hydrogen generation under visible light irradition in the case of Rh-doped titanate/porphyrin hybrids.
