Preparation and Characterizations of Na₂Ti₃O₇, H₂Ti₃O₇ and TiO₂ Nanobelts

Abstract:

In this paper, the Ti-O-Compound nanobelts from commercial TiO₂ (annatase phase) were synthesized via the alkali-hydrothermal process. The as-synthesized nanobelts are sodium titanate, hydrogen titanate and anatase with general formula Na₂Ti₃O₇, H₂Ti₃O₇ and TiO₂, respectively. The nanobelts are characterized by Thermogravimetric/Differential Thermal Analysis (TG/DTA), X-ray Diffraction (XRD), Infrared Spectra (IR) and Scanning Electron Microscope (SEM) apparatuses. The characterization indicates that the nanobelts with typical widths of 50 to 200 nm, thicknesses of 20 to 50 nm, and up to a few millimeters in length. The conversion mechanisms between the layer titanate and anatase of nanobelts have been discussed in this study.
