Summary:A simple but effective hydrothermal intercalation and exfoliation route is developed to prepare ultrathin M0S2 nanosheets in high yield. The morphologies and microstructures of as prepared products are characterized by X-ray powder diffraction, transmission electron microscopy, scanning electron microscopy and atomic force microscopy. It is found that zerovalent lithium is readily intercalated between the layers of MoS(2) using ethylene glycol as both reductant and solvent in hydrothermal process. Subsequently ultrathin MoS(2) nanosheets with good quality are obtained by the removing of lithium via the exfoliating process in water. The obtained ultrathin MoS(2) nanosheets exhibit preferable photoelectrochemical and photoresponse activity under the illumination of simulated sunlight compared to bulk MoS(2). Our results indicate that ultrathin MoS(2) nanosheets have promising applications in photo-electrochemistry, heterogeneous catalysis, sensors and optoelectronic nanodevices.
