Relationship of Titania Nanotube Binding Energies and Raman Spectra

Abstract

Abstract-Novel nanostructured titania nanotubes and hydrogen titanate nanoribbons were synthesised using hydrothermal treatment of Degussa P25. The nanostructure types formed were monitored as a function of the hydrothermal conditions. Changes in structure was evaluated using X-ray photoelectron spectroscopy (XPS), powder X-ray diffraction (XRD), Transmission electron microscopy (TEM) and Raman spectroscopy.X-ray photoelectron spectroscopy (XPS) of Ti(2p 3/2 ) and O(1s) binding energies in titania nanotubes were measured and a systematic trend in the XPS binding energies was observed. This indicated a strengthening of the Ti-O bond occurred as the material phase changed from titania nanotube to the titanate ribbon form. The changes in binding energies for both the Ti and O XPS peaks were consistent with changes observed in the Raman spectra of nanostructured titania.

“…The nanoparticle coating that is often used is Titanium dioxide or TiO 2 [8]. The large band gap energy (Eg) value of 3.20 eV, good chemical stability, non-toxicity, environmental compatibility and low price are the advantages of the TiO2 semiconductor material [9]. The anatase structure of TiO 2 can be used as an electrode in solar cells, lithium batteries and electrochromic devices [10].…”
