Outline of Final Research Achievements

It is important to fabricate innovative photofunctional materials and understand the fundamental reaction mechanisms for developing an efficient light energy conversion system. In this project, we have synthesized porous metal oxide mesocrystals and modified them with various nanomaterials to improve the photocatalytic activity. For example, plasmonic Au nanoparticle-modified titanium dioxide mesocrystals were found to have greatly improved visible light photocatalytic activity owing to an efficient interparticle electron migration in the mesocrystal structure. Furthermore, we have developed a facile method for synthesizing different kind of mesocrystals and their composites.
