Valence controlled TiO_2 nanoparticles and ZnO nanoparticles can be used as transparent electroconductive materials and UV shielding materials. They also show photocatalytic activity. In order to improve these characteristics, it is important issue to control orientation of the crystallites in sintered compacts and thin films. Stable dispersion of the oxide nanoparticles in solution is essentially important to obtain uniform thins films.In this study, valence controlled TiO_2 nanoparticles and ZnO nanoparticles were prepared by solution process with low temperature heating process. Furthermore, the nanoparticle formation process was carried out in a cellulose tube. The dialysis processes with cellulose tube enabled to obtain the oxide nanoparticles with stable dispersion in a aqueous solution since the formation and growth process was occurred with reducing the impurity ions by dialysis process.Furthermore, the nanosheet particles of Nb^<5+> - doped titanic acid was easily obtained and the highly oriented Nb5+ - doped TiO_2 was formed by only coating process on substrate.

价态控制的TiO_2纳米颗粒和ZnO纳米颗粒可用作透明导电材料和紫外屏蔽材料。它们还表现出光催化活性。为了改善这些特性，控制烧结体和薄膜中微晶的取向是重要的问题。氧化物纳米颗粒在溶液中的稳定分散对于获得均匀的薄膜至关重要。本研究采用低温加热溶液法制备了价态控制的TiO_2纳米颗粒和ZnO纳米颗粒。此外，纳米颗粒的形成过程是在纤维素管中进行的。利用纤维素管的透析过程能够获得在水溶液中稳定分散的氧化物纳米颗粒，因为通过透析过程减少杂质离子的同时发生形成和生长过程。此外，Nb^<5+>掺杂的纳米片颗粒钛酸容易获得，仅通过在基体上涂覆工艺即可形成高度取向的Nb5+掺杂TiO_2。
