Integration of novel environmental-friendly and energy creation functions to oxide nanotubes through low-dimensional nanoarchitecture control

为了使钛纳米管（TNTs）成为一种新型的多功能环境和能源材料，对其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，明确并增强了分子吸附与光化学性质的协同作用。当尺寸可控的tnt用于染料敏化太阳能电池时，实现了染料吸附增强和跟随剂效率的提高。金属掺杂和金属纳米颗粒负载的tnt也得到了发展。结果表明，这些改性后的TNT具有较好的物理光化学功能，并且在能量传递过程中具有独特的多功能性，并明确了其作为光催化剂的可见光责任。这些结果证明，目前的低维纳米结构氧化物的结构控制是一种很有前途的新材料和新系统的方法。

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.
