摘要：

Vanadium oxide nanotubes (VOx-NTs) were prepared by using V2O5 sols as precursor for the first time with hexadecylamine (HDA) as structure-directing template via a modified sol-gel method followed by hydrothermal treatment. Structure and morphology of the nanotubes were investigated by XRD, SEM, HRTEM, TGA, FT-IR and XPS. The obtained nanotubes were found having outer diameters from 30 to 100 nm and inner diameters from 10 to 30 nm with length up to several micrometers. It is also confirmed that water molecules enter vanadium oxide layers together with structure-directing template and the low valence vanadium occurs in the VOx-NTs. (C) 2004 Elsevier B.V.
