Abstract

Flowerlike MoS₂ nanoparticles have been successfully synthesized through a mild solvothermal reaction with the aid of ethanol aqueous solution, and the samples have been characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and low temperature nitrogen adsorption-desorption. The nanometer flower MoS₂ is composed of ultrathin nanosheets of approximately 10 nanometers in thickness. The influence of the reaction temperature and the reaction time on the formation of the flowerlike MoS₂ nanoparticles were evaluated. The optimal experimental conditions were determined as follows: the molar ratio of 1∶1 between ethanol and water, the reaction temperature of 190°C, and the reaction time of 24 h.
