摘要：
This paper demonstrates an ethanol gas sensor based on indium oxide/molybdenum disulfide (In2O3/MoS2) nanocomposite via hydrothermal route. The microstructure and micromorphology of In2O3/MoS2 nanocomposite were fully characterized by various analytical techniques. The gas-sensing properties of the In2O3/MoS2 composite were investigated upon exposure to different concentrations of ethanol gas from 1 ppm to 50 ppm at the optimum temperature, and compared with the pristine In2O3 sensors. Owing to the supporting substrate of specific two-dimensional MoS2 nanosheets, the sensor based on In2O3/MoS2 composite exhibit superior gas sensing performance towards ethanol, which outstripped that of pure In2O3 sensor and have potential applications in the detection of ethanol vapors.
