摘要：

Tungsten oxide nanorods have been prepared by a simple microwave hydrothermal (MH) method via Na2SO4 as structure-directing agent at 180 degrees C for 20 min. The structure and morphology of the products are characterized by X-ray powder diffraction (XRD) and transmission electron microscopy (TEM). The obtained nanorods are about 20-50 nm in diameter and several micrometers in length. The ethanol sensing property of as-prepared tungsten oxide nanorods is studied at ethanol concentration of 10-1000 ppm and working temperature of 370-500 degrees C. It was found that the sensitivity depended on the working temperatures and also ethanol concentration. The results show that the tungsten oxide nanorods can be used to fabricate high performance ethanol sensors. (C) 2010 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
