| description | <p>Abstract</p><p>MoS<sub>2</sub>nanofiber bundles have been prepared by hydrothermal method using ammonium molybdate with sulfur source in acidic medium and maintained at 180 °C for several hours. The obtained black crystalline products are characterized by powder X-ray diffraction (PXRD), Fourier transform infrared spectrometer (FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The PXRD pattern of the sample can be readily indexed as hexagonal 2H-MoS<sub>2</sub>. FTIR spectrum of the MoS<sub>2</sub>shows the band at 480 cm<sup>−1</sup>corresponds to the γ<sub>as</sub>(Mo-S). SEM/TEM images of the samples exhibit that the MoS<sub>2</sub>nanofiber exist in bundles of 120–300 nm in diameter and 20–25 μm in length. The effects of temperature, duration and other experimental parameters on the morphology of the products are investigated.</p> |
