| Research Abstract |
To improve the photocatalytic activity it is important to improve the separation efficiency of the electron and the hole generated at the light irradiation. In this study, the new synthesis method for the hollow photocatalytic particles supported precious metal nanoparticles uniformly and densely onto their inner surface using the microbial cells as templates has been proposed, and the photocatalytic activity was investigated. As a result, the synthesis of hollow titania particles using yeast cells supported platinum nanoparticles as templates has been succeeded, and the photocatalytic activity was found to be about four times as high as that of dense particles supported platinum nanoparticles onto their surface.
