| Abstract | Tin disulfide belongs to the class of layered materials and has drawn attention because of its unique surface properties. In this report, synthetically prepared bulk precursor has been used to fabricate 2D layered hexagonal SnS 2 flakes by using liquid exfoliation technique. It was evident from structural and morphological characterization that the exfoliation produces aggregated flakes of SnS 2 . The prepared 2D SnS 2 based sensor has shown a response toward NO gas at room temperature, whereas the bulk SnS 2 based device doesn't respond to any analyte. The device employing exfoliated SnS 2 flakes as sensing layer responds to NO in the concentration range of 500 ppb (20.61%) to 2.75 ppm (163.32%). Moreover, the sensor offers highly stable and repeatable performance with little drift. This study implements an efficient route for nanoflakes synthesis from bulk layered SnS 2 by the liquid exfoliation and the result of sensing test can stimulate in the production of high performance NO gas sensors |
