Abstract

Porous titania (TiO2) was synthesized under ultrasonic vibration via an anodic oxidation of titanium metal in various kinds of electrolyte such as HNO3, H2SO4, and their mixture. HNO 3 resulted in amorphous or poorly-crystalline particles with mesopores while H2SO4 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.
