| Outline of Final Research Achievements |
In this study, confirmation of the production of carbon monoxide, which is responsible for realization of the proposed cycle, is an important step. Titania-based photocatalysts were prepared under various conditions and the state of the loaded metals was confirmed by XRD, XPS and so on. Photocatalytic activity was performed under various conditions, then, it is found that those photocatalysts discolored immediately after light irradiation. Although it could be confirmed that some kinds of reaction occurred, some problems were raised: the irradiation light source, reaction reactor, and the solid photocatalyst itself did not uniformly react due to anisotropic light irradiation. As a result, the target carbon monoxide production couldn’t be confirmed. and it was impossible to confirm clearly the state of the sample after the reaction.
