Synthesis of WO3Nanoparticles

`WO3 Nanowires were fabricated by a hydrothermal method in the presence of 2 4 K SO . The nanowires exhibit a well crystallized one dimensional structure with 50 nm in diameter and several microns in length. Effects of other alkali salts ( 3 KNO , 3 NaNO and 2 4 Na SO ) on the morphologies of 3 WO nanocrystals were also investigated. The important role of 2 4 K SO salt in the 3 WO nanowires synthesis has been demonstrated. The resultant 3 WO nanoparticles have been investigated with X-ray diffraction (XRD), transmission electron microscopy (TEM)
