| Abstract
| - Template precipitation of TiO2 in AAM renders an anatase nanostructure of compact rods of 200−250 nm wide with particle size of 20 nm, encompassed by fragile tubules of wall thickness of the same size as their particle size, i.e., 60−80 nm, with the composite rod−tubule being 2.5 times wider than the pore size of the AAM.
- Composite anatase TiO2 nanostructure, consisting of both tubules and rods, has beensynthesized by precipitation from hydrolyzed TiCl4 solution using an anodic aluminamembrane (AAM). SEM analyses show that the structure consists of rods of 200−250-nmdiameter and tubules of about 500-nm diameter. Each tubule may be visualized as a singlesheet of 60−80 nm thickness rolled into a cylinder of diameter about 2.5 times the pore sizeof the AAM. The thus-prepared TiO2 nanomaterial is characterized and a possible mechanismof its formation is discussed.
