Structure of nanosize materials by high-energy x-ray diffraction: study of titanate nanotubes

Abstract

High-energy X-ray diffraction and atomic Pair Distribution Function analysis are employed to determine the atomic-scale structure of titanate nanotubes. It is found that the nanotube walls are built of layers of Ti-O6 octahedra simular to those observed in crystalline layered titanates. In the nanotubes, however, the layers are bent and not stacked in perfect registry as in the crystal. © 2007, Oldenbourg Wissenschaftsverlag
