Abstract
U
nique WO 3 nanorod s w ere synt hesized successfully via a novel one step hydrothermal method with the assistance of
potassium sulfate K 2 SO 4 The WO 3 nanorod s had uniform size with diameters around 30 nm and length up to 100~250nm.
Moreover, it was surprisingly noticed that the K 2 SO 4 played a key factor on fabrications of WO 3 nanorod s . A possible growth
mechanism of th e WO 3 nanorod s was also proposed. We found that the WO 3 nanorod s show ed excellent gas sensing
performances towards ethanol The facile preparation method and the improved properties derived from the one dimensional
structures of nanorod s are significant in the synthesis and future applications of functional nanomaterials..
