摘要
Amorphous WS2 has been prepared by ultrasound irradiation of W(CO)(6) solution in diphenylmethane (DPhM) in the presence of a slight excess of sulfur at 90 degreesC under argon. Heating the amorphous powder at 800 degreesC under argon yields WS2 nanorods and their packings. The average size of WS2 nanorods was found to be 3-10 nm and 1-5 mum in thickness and length, respectively. The prepared WS2 has been characterized by elemental analysis, X-ray powder diffraction measurements, FTIR spectroscopy, differential scanning calorimetry, thermogravimetric analysis, transmission electron microscopy, scanning electron microscopy, atomic force microscopy and energy dispersive X-ray analysis.
