Title: Spectroscopic and microscopic study of vanadium oxide nanotubes

Abstract

V{sub 2}O{sub 5} nanotubes synthesized via the sol-gel route has been studied by electron energy loss spectroscopy (EELS), x-ray absorption spectroscopy (XAS), and energy dispersive x-ray analysis, in order to understand the local structure of vanadium in the nanotubes. Contrary to our expectation, all the features of the XAS and EELS spectra of the V{sub 2}O{sub 5} nanotubes are in line with that of bulk layered vanadium oxide revealing that vanadium is present in the 5{sup +} oxidation state in the nanotubes. However, V{sub 2}O{sub 5} nanotubes exhibit additional surface states in their electronic structure in comparison with bulk V{sub 2}O{sub 5}. A comparison of measured and calculated spectra allows us to distinguish single-wall from multiwall V{sub 2}O{sub 5} nanotubes.
