| Abstract
| - TiO2 tubules are synthesized using a template method accompanied by hydrolysis by water vapor. Titanium isopropoxide is used as a dipping solution instead of titania sol (usually used). The remaining titanium isopropoxide left coating the walls of the pores of template (alumina membrane) is then hydrolyzed by water vapor.
- TiO2 nanostructures are prepared using a template method involving synthesis of TiO2within pores of a nanoporous membrane. In this study, template synthesis is accompaniedby hydrolysis by water vapor in the preparation of TiO2 nanotubules. These TiO2 nanotubulesare prepared within the pores of an alumina template membrane. Characterization of theTiO2 tubules is accomplished by infrared spectroscopy (IR), UV−Vis spectrometry (UV), X-raydiffraction (XRD), scanning electron microscopy (SEM), and transmittance electron microscopy (TEM). TiO2 nanotubule diameters of ca. 50 and 200 nm were found. The 50-nm-diameter nanotubules were polycrystalline of anatase, and the 200-nm-diameter nanotubuleshad a thickness of 10 nm. This new method based on template synthesis and hydrolysis bywater vapor can fabricate smaller TiO2 nanotubules easier than sol−gel template synthesis.
