Preparation of MoS2 Microspheres with Different Proportions by Hydrothermal Method and their Gas Sensing Performance
Keywords:MoS2, Different proportions, Gas sensing performance
MoS2 microspheres with three different proportions were prepared by hydrothermal method. The effects of different proportions on the morphology, purity and sensing performance of MoS2 were studied. The morphology and structure of MoS2 were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The results show that the MoS2 microspheres with the best morphology and the highest purity can be obtained when the ratio of Mo to S is 1:2. The results of gas sensitivity test show that the optimum working temperature of the three samples is 175?. When the ratio of Mo to S is 1:2, the sensitivity to 100ppm-500ppm ethanol gas is obviously better than other ratios.
