Main Research Field

Nano Chemistry

We use various methods to synthesis nanostructured materials and try to understand their formation mechanism, physical properties, both experimentally and theoretically. We investigate the reactivity and modification of nanotubes and nanostructured materials for application purposes, such as field emission display, fuel cell, LED, etc.


Particular Research

Functional nanomaterials
Research interests of our group, the Functional Materials Laboratory, are various aspects of science and technology, ranging from fundamental research to possible industrial applications. Our researches are focused on design and synthesis of noble nanoporous materials, especially mesoporous materials, and nanostructured materials such as nanoparticles and nanowires. The nanoporous materials have attracted much attention in the fields of nanochemistry, nanotechnology, and supramolecular chemistry due to their ordered nanoporocity (1 - 30 nm). Generally, the nanoporous materials are synthesized by self-assembly and polymerization between organic pore generator and inorganic framework precursors. We have been developing new synthetic strategies for the materials in order to give new structures and functionalities. Applications of the nanoporous materials as the catalytic and electronic materials are also our main interests
