Outline of Final Research Achievements

In this study, photocatalytic activities of dye-sensitized TiO2-based catalysts for hydrogen production from aqueous solutions containing sacrificing substances were examined under visible-light irradiation. We have found that an indoline-type dye having two anchors showed a relatively stable photocatalytic activity for this reaction. Because of its hydrophobic property, the catalysts with larger amounts of the dye were not dispersed sufficiently in the aqueous solution and hence showed lowered activities. We also found that the catalyst with silica-modified TiO2 instead of TiO2 were dispersed well in the aqueous solution and showed a significantly improved photocatalytic activity.
