A solution low-temperature route to MoS2 fiber

MoS2 fiber has been synthesized through a solution low-temperature route, s tarting from the precursor (NH4)(2)Mo3S13 in ethylenediamine. X-ray diffrac tion of the product shows that it is amorphous. After annealing took place, the results indicated that morphologies of the MoS2 were kept and the MoS2 crystallized The MoS2 products were also characterized by transmission ele ctron spectroscopy, selected area electron diffraction, X-ray photoelectron spectroscopy, and W-vis absorption spectroscopy. A mechanism of the format ion of fiber is proposed.
