Description
A novel route for the preparation of Na2Ti6O13 nanobelts by mechanochemical treatment of the TiCl4-Na2SO4.10H2O-Na2CO3 mixture for 5 min followed by molten salt synthesis is described. The mixture of the amorphous TiO2 and NaCl-Na2SO4.xH2O-Na2CO3 salt matrix was generated during milling. The molten salt synthesis of the Na2Ti6O13 nanobelts with lengths up to 0.5-2 μm and with a width in the range of 20-250 nm was carried out in the temperature range of 700-800 oC for 1 h. The partial formation of titanate nanotubes was observed after annealing at 600 oC and washing procedure. X-ray diffraction (XRD), transmission electron microscopy (TEM) and differential thermal analysis (DTA) were used to characterize the formation and structure of Na2Ti6O13 nanobelts.
