Vanadium oxide nanotubes (Vox-NTs) have been synthesized by using n-butylamine as structure- directing template and V2O5 as precursor under hydrothermal conditions. XRD, FTIR, SEM, TEM, BET and TG-DTA characterizations have been performed to both optimize the synthetic conditions and understand the growth mechanism of Vox-NTs. The results showed that open-ended Vox-NTs were obtained under the optimized conditions (hydrothermal temperature: 150-160°C, hydrothermal time: 5-7 d, the molar ratio of V2O5 to n-butylamine is 1:1) with diameters ranging from about 30 to 100 nm and several micrometers in length. The BET surface area and the desorption cumulative pore volume of pores of the as-synthesized sample were about 27.4609 m2/g and 0.191087 cm3/g, respectively. The result presents that the synthesis of Vox-NTs is controlled by the "rolling" mechanism and temperature is primary driving force for rolling.
