Abstract:
The adsorption behaviour of ammonium ions and the structural features of layered proton trititanate were characterised by using Raman spectroscopy, X‐ray diffraction (XRD) and transmission electron microscopy. It revealed that the intensity of the Raman band at 309 cm −1 , assigned to very long TiO bonds (0.22 nm), reduced, whereas the band at 890 cm −1 , assigned to very short TiO bonds (0.17 nm), increased slightly after the adsorption of ammonium ions (NH 4 + ). The adsorption of ammonium ions enlarged the interlayer distance of the (200) plane. Ammonium ions were located at the corner of the TiO 6 octahedral slabs. This was further confirmed by XRD, with an increased intensity of the (20 1 ) plane being observed. Copyright © 2010 John Wiley & Sons, Ltd.
