| Outline of Final Research Achievements |
The TiO2/SiO2 composites supporting fine metal particles consisting of Pt and group 11 elements have been prepared in various conditions by the calcination of the precursors (TiO2/SiO2 composites adsorbing various amount of mixed-metal complexes consisting of Pt and group 11 elements). The photocatalytic activities of these TiO2/SiO2 composites supporting fine metal particles were evaluated by using aqueous solution of methylene blue. We found that the fine metal particles supported photocatalyst containing Pt and Au showed very efficient activity. The surface structures of the photocatalysts were elucidated by the STEM observations.
