Abstract High-purity MoS₂ nanosheets have been synthesized by thermal sulfuration method. The phase and morphology of the samples were characterized by X-ray diffraction, Raman spectrometer, scanning electron microscope and energy dispersive spectrometer. The effect of reaction temperature on the MoS₂ nanosheets was analyzed. The photo sensitive and gas sensitive properties of MoS₂ were studied. It was found that the nanosheets was more sensitive to the green light than the red light. High sensor response and fast response/recovery time to methanol, ethanol were observed in MoS₂ nanosheets based device, and its gas sensing mechanism was discussed.

Key words： molybdenum disulfide nanosheets photo sensitive gas sensitive
