Preparation of Titania Nanotube Arrays by the Hydrothermal Method

Abstract

Abstract: Titania nanotube arrays synthesized through hydrothermal treatment assisted with an anodic aluminum oxide template exhibit an especial morphology, that is, a co ntinuous porous surface and discrete tubular cross-section structure. The forma tion of such an especial morphology is attributed to preferential deposition of the hydrolysis product on the surface of the template, which is caused by the di fferent reaction rate when ［TiF6］2- reacts with the surface and the c ross section of the template.

Key words: titania, nanotube arrays, hydrothermal reaction, anodic aluminum oxide template, formation mechanism
