TLDR
In this paper, the atomic structure of the synthesized tubular material is imaged by high-resolution transmission electron microscopy (HRTEM), and the composition of individual tubular structures is determined using selected area energy dispersive X-ray spectroscopy (EDX).Abstract:
Well crystallized nanoscale tubular materials have been synthesized via the reaction of TiO2 crystals of either anatase or rutile phase and NaOH aqueous solution. The atomic structure of the synthesized tubular material is imaged by high-resolution transmission electron microscopy (HRTEM), and the composition of individual tubular structures is determined using selected area energy dispersive X-ray spectroscopy (EDX). Our results show that the tubular materials are well crystallized tubes with an average diameter of about 9 nm and little dispersion, and are composed of mainly titanium and oxygen. The atomic ratio of O/Ti is found, however, to vary from tube to tube. Detailed electron and x-ray diffraction studies show that the structure of our titanium oxide nanotubes do not agree with those made of TiO2 crystals with either anatase or rutile phase. HRTEM observations revealed that the titanium oxide nanotubes usually have multiple shells, in analogy with multiwalled carbon nanotubes, but the shell spacin...read more

B-doped TiO 2 nanotubes and its photocatalytic activity
TL;DR: Two-step hydrothermal method was developed to prepare B-doped TiO2 nanotubes (BTNTs) by TEM, XRD, XPS, FT-IR, UV-Vis spectroscopy, its photocatalytic activity was evaluated by the degradation of methyl orange (MO) aqueous solution both under UV light and visible light irritation as discussed by the authors.

One-Step Hydrothermal Synthesis and Characterizations of Titanate Nanostructures
TL;DR: In this paper, it was shown that a nanotube made from a three-dimensional compound cannot form a fully crystalline structure and the surface is normally active, since all the chemical bonds of the threedimensional compound will not fully satisfy on the nanotubes surfaces so that to form a perfectly ordered, flawless nanotubular structure.
