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.

为了使二氧化钛纳米管（TNTs）成为新型多功能环境和能源材料，进行了各种工艺优化、结构修饰和功能分析。通过工艺优化成功合成了尺寸可控的TNT，并阐明和增强了分子吸附和光化学性质的协同作用。当尺寸受控的TNT用于染料敏化太阳能电池时，实现了增强的染料吸附和跟随器效率的增加。还开发了金属掺杂和金属纳米颗粒负载的TNT。结果发现，这些改性TNT表现出更好的物理-光化学功能，并发现独特的多功能性的能量传递过程以及可见光响应的光催化剂被澄清。这些结果表明，目前的低维纳米结构氧化物的结构控制是有前途的新材料和系统的方法。
