| Research Abstract |
Solar water splitting using photocatalysts is a promising technology for energy conversion and storage. However, design concepts for highly efficient photocatalyst have not been clarified even in the case of a widely used TiO2 photocatalyst. Elucidating correlations between structure, physical properties, and photoexcited electron lifetime will provide the design concepts of highly efficient photocatalysts. In this study, we investigated the decisive factors deciding the photocatalytic activities of TiO2 and WO3 using time-resolved infrared absorption spectroscopy evaluating photoexcited electron lifetime.
