dc.description.abstractA detailed study on the structural deformation of trititanate nanofibers after the adsorption of divalent strontium (Sr) and barium (Ba) cationswas conducted by using Raman spectroscopy, X-ray diffraction (XRD) and transmission electron microscopy (TEM). It was found that the Raman bands at 309 cm-1 corresponding to very long Ti-O bonds (2.2 ũ and at 883 cm-1 corresponding to the very short Ti-O bonds (1.7 ũ decreased in intensity after the adsorption of Ba2+ and Sr2+ cations. Additionally, the band at 922 cm-1 corresponding to an intermediate length Ti-O bond was observed to weaken with the adsorption of divalent cations, indicating that the TiO6 octahedra in Na2Ti3O7 aremore regular. These results suggest that the active sodium (Na+) cations in Na2Ti3O7 should be located at the corner of the TiO6 octahedral slabs, i.e. the plane (003). This was further confirmed by a large decrease of diffraction intensity of the plane (003) observed in the XRD pattern.
