| Outline of Final Research Achievements |
We have studied a new metal nanoparticles/metal oxide semiconductor photocatalyst that promotes organic transformations based on the absorption of visible region light by metal nanoparticles. Platinum (Pt) nanoparticles produces photoactivated “hot electrons” by an absorption of visible light by the interband transition of their d electrons; however, there is no report of Pt nanoparticles applying to photocatalytic reactions. We have found that Pt/TiO2 and Pt/Ta2O5 systems, when absorbing visible light, efficiently produces hot electrons and promotes several organic transformations with very high quantum yields.
