Abstract
A very simple molten-salt method was used to synthesize WO3 nanotubes at moderate temperature (600 °C). The outer and inner diameters of the WO3 nanotubes were about 100 nm and 30 nm,with a length of dozens of micrometers. TEM and XRD analyses showed that the WO3 nanotubes were single crystal, and had monoclinic structure with the axes preferentially aligned along the [011] direction. The photoluminescence and the gas sensitivity of the nanotubes had been tested, showing that the products very well responded to acetone at 340 °C.
