价控纳米二氧化钛和氧化锌纳米颗粒可用作透明导电材料和紫外线屏蔽材料。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的微晶取向是一个重要的问题。氧化物纳米颗粒在溶液中的稳定分散是获得均匀薄膜的关键，本研究采用低温加热溶液法制备了价控纳米二氧化钛和氧化锌纳米颗粒。此外，纳米颗粒的形成过程是在纤维素管中进行的。纤维素管透析法通过透析法还原杂质离子的形成和生长过程，可以得到在水溶液中分散稳定的氧化物纳米颗粒，而且Nb~(2+)、Lt；5+、Gt~(2+)掺杂的钛酸纳米粒子很容易得到，而且只需在衬底上包覆一层就可以得到高度取向的掺Nb~(5+)纳米二氧化钛。

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.
