Synthesis of one-dimensional sodium titanate nanostructures

We synthesized sodium titanate nanotubes and nanowires using TiB2 and TIN as the starting materials, respectively in a hydrothermal process. The experimental results indicate that the reaction temperature influences the morphology of the product significantly. The nanowires were formed above 170 degrees C. Nanotubes were obtained below 140 degrees C. The synthesized nanotubes exhibit a crystallized multi-wall structure. The inner diameter was found to be ca. 5 nm. The diameter of the nanowires was found to be ca. 50 nm. The characteristic lengths was in the order of tens micrometers.
