| Outline of Final Research Achievements |
We defined “hierarchical function” as a function in which each level in a hierarchical structure interplays with each other by exchanging or passing chemical species (molecules or ions), charges (electrons and/or ions), or mechanical forces (compressing and tensile stress) etc. through the interfaces. In this study, we focused on such functions in inorganic crystals and nanostructured materials. Our study results include intentionally constructed WO3 crystal-TiO2 nanocrystals contacts, TiO2 crystallites surrounded by mesoporous silica for enhanced photocatalysis, analysis of control factors of ionic conductivity in mesostructured composite of metal oxides and Li salts, and functions of intermetallic compound crystals in which one moiety passes charges to another moiety in the crystal structure.
