Synthesis and Thermal Stability of One-dimensional Titanate Nanotubes
In the present work, a novel titanate (H2Ti5O11·3H2O) nanotubes are synthesized by a simple hydrothermal method, and their thermal stability such as the phase transformations and microstructures change are also studied. The as-grown samples are heated in the air at 300-800℃. The titanate nanotubes will be completely destroyed when the temperatures are above 600℃, which show that the present titanate nanotubes possess good thermal stabilization. The experiment results reveal that the phase transformations and microstructure changes of present titanate nanotubes follow the process from titanate nanotubes to anatase and rutile TiO2 nanobelts, the Na2Ti6O13 nanwires are formed over 700℃.
