概要
- 論文の詳細を見る
Porous titania (TiO_2) was synthesized under ultrasonic vibration via an anodic oxidation of titanium metal in various kinds of electrolyte such as HNO_3, H_2SO_4, and their mixture. HNO_3 resulted in amorphous or poorly-crystalline particles with mesopores while H_2SO_4 resulted in dense and crystalline film with macropores. Ultrasound in general decreased the maximum voltage, film thickness, and a rutile phase, while it increased the region for the formation of mesoporous structure. Role of ultrasound on the anodic oxidation is discussed.
