Abstract
SnS2 nanosheets decorated with SnO2 nanocomposites have been successfully prepared by in-situ high-temperature oxidizing pristine SnS2 in air at 300 °C. The formed SnO2/SnS2 heterojunction based chemiresistive gas sensor exhibits an excellent sensitivity and selectivity to different concentrations of NO2 from 1 ppm to 8 ppm at 80 °C. The higher response of the as-fabricated SnO2/SnS2 heterojunction based sensor to NO2 compared with that of the pure SnS2 based one could be attributed to the extra charge transfer between SnO2/SnS2 interfaces.
