摘要：

Ultrathin MoS2 nanosheets with thickness of 5-10 nm were successfully synthesized by a facile gas-solid reaction method, using molybdenum trioxide (MoO3) and thiourea as the precursors, and then calcined at 800-850 degrees C under 1 13 for 1 h. As-prepared MoS2 samples were characterized by XRD, EDS, FESEM, and TEM. TEM and FESEM results showed that the obtained MoS2 ultrathin nanosheets mainly consisted of 5-10 layers stacking of the monatomic sheets. The influence of temperature on the formation of MoS2 nanosheets was investigated. A possible two-step reaction mechanism is proposed to explain the formation of MoS2 nanosheets on the basis of observations of a temperature-dependent morphology evolution process.
