摘要：

Using anodized TiO2 nanotubes as the starting materials, unique structural single-crystalline anatase TiO2 dous assembled microspheres are fabricated by a hydrothermal method. The single-crystalline anatase TiO2 dou is formed through the transformation of a TiO2 nanotube, which is formed through a complex process including the expansion of the nanotube, dissolution-recrystallization, and recombination. The opening and hollow structural dou exposes one {001} face and eight {101} faces, which displays excellent photocatalytic activity. And it is also envisaged to be of high promise for many other potential applications. The approach might be exploited for the synthesis of single-crystalline nanomaterials with special morphologies.
