One-pot hydrothermal synthesis of MoS2 nanosheets/C hybrid microspheres

Uniform MoS2 nanosheets/C hybrid microspheres with mean diameter of 320 nm have been successfully synthesized via a facile one-pot hydrothermal route by sodium molybdate reacting with sulfocarbamide in ID-glucose solutions. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX). XRD patterns showed that the MoS2 was kept as a two-dimensional nanosheet crystal and C was retained as amorphous even after their annealing treatment at 800 degrees C. TEM and SEM images indicated that the MoS2 nanosheets were uniformly dispersed in the amorphous carbon. The experiment results also revealed that the appropriate amount of D-glucose had an obvious effect on the formation of uniform MoS2 nanosheets/C hybrid microspheres. A possible formation process of MoS2 nanosheets/C hybrid microspheres was preliminarily presented. (C) 2011 Elsevier Ltd and Techna Group Sri. All rights reserved.
