| Research Abstract |
To facilitate titania nanotubes (TNTs) as for the novel multifunctional environmental and energy materials, various process optimization, structure modification and function analyses were carried out. Size-controlled TNTs were successfully synthesized by process optimization, and synergy of molecular adsorption and photochemical properties were clarified and enhanced. When the size-controlled TNTs were used for dye-sensitized solar cells, enhanced dye adsorption and follower efficiency increase was achieved. Metal-doped and metal nanoparticles loaded TNTs were also developed. It was found that these modified TNT exhibited better physico-photochemical functions, and also found that unique multifunctionalities in energy transfer processes as well as visible light responsibility as the photocatalyst were clarified. These results rationalize that the present architecture control of low-dimensional nanostructured oxides is promising method for novel materials and systems.
