  The formation and crystal structure of sodium   titanate nanobelts synthesized with variousTi precursors are   reported. P25(TiO2)   powder, Ti(OBu)4, and TiCl4 were   used as Ti precursors.Their nanobelts were synthesized via   hydrothermal process at 180°C   for24h in concentrated aqueous NaOH solution.The productobtained   with P25(TiO2) was   identified to be Na2Ti4O9 ·1.5H2O. The   products obtained with Ti(O(CH2)3CH3)4 and   TiCl4 were confirmed to be the crystal structure of   Na2Ti2O4(OH)2. This   means that the formation mechanism of the crystal structure in   the synthetic process depends on their Ti source. Their   morphology was compared with XRD, TEM, FE-SEM, Raman, and TGA. On   the basis of their morphology results, the crystalline structure   model and the formation mechanism of sodium titanate nanobelts   are proposed.
