摘要：

Composite anatase TiO2 nanostructure, consisting of both tubules and rods, has been synthesized by precipitation from hydrolyzed TiCl4 solution using an anodic alumina membrane (AAM). SEM analyses show that the structure consists of rods of 200-250-nm diameter and tubules of about 500-nm diameter. Each tubule may be visualized as a single sheet of 60-80 nm thickness rolled into a cylinder of diameter about 2.5 times the pore size of the AAM. The thus-prepared TiO2 nanomaterial is characterized and a possible mechanism of its formation is discussed.
