摘要：
MoS2 nanosheets have been prepared by a rapid and simple microwave-assisted wet-chemical method using MoS2, LiOH.H2O and ethylene glycol as the raw materials. The structure and morphology of the obtained product have been characterized by X-Ray diffraction (XRD), kaman spectroscopy, Atomic force microscopy (AFM), transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HRTEM). The thickness of the MoS2 nanosheets is about 4.42 nm. The MoS2 nanosheets after cold pressing have a low electrical conductivity and a high Seebeck coefficient of 690 mu V/K. The Seebeck coefficient is much higher than that (280 mu V/K) of raw MoS2 powders. In addition, the MoS2 nanosheets have enhanced capacitive performance compared with the raw MoS2 powders, too.
