概要
- 論文の詳細を見る
TiO2 particles were prepared in aqueous solutions at 50°C. They were in a single phase of anatase TiO2 and about 800 nm in diameter. They were constructed of nano TiO2 crystals to have nano-sized relief structure on surfaces. TiO2 particles exhibited N2 adsorption-desorption isotherms of type I. BET specific surface area of the particles was estimated to 168 m2/g. The particles were prepared without high temperature annealing which caused aggregation and crystal growth of particles. It was confirmed that the solution process has a high ability to prepare anatase TiO2 particles having high BET surface area.
