Abstract
The structure of Nb2O5 nanotubes was studied by electron diffraction and high-resolution transmission electron microscopy (HRTEM). The nanotubes were prepared from highly crystalline-layered K4Nb6O17 crystals grown from a KCl flux using the intercalating and exfoliating techniques. Nanotubes have a length of about 200nm and a diameter of 20 nm. The observed electron diffraction patterns revealed that the nanotubes have a helical structure with the basal plane of (010) and the tube-axis parallel to the [201] direction. Their basal plane corresponds to the (010) plane of the layered K4Nb6O17 crystals. The helical lattice plane was directly observed by a Fourier filtered HRTEM image.
