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.
