Abstract:

One-dimensional titanate nanomaterials were synthesized by a hydrothermal reaction using different titania sources. The morphology and crystal structure of the one-dimensional titanate nanomaterials were greatly affected by the primary particle size and crystal structure of the starting materials. The smaller initial particle size of the reactant led to a faster phase transformation of the products. The pure anatase titania favored the formation of titanate nanotubes, while the mixture of anatase titania and a small amount of rutile titania as a starting material favored the further transformation of nanotubes to nanowires or nanoribbons and promoted the phase transformation.

Key words: Titanate, One-dimensional nanomaterials, TiO2, Hydrothermal method, Morphology, Crystal structure
