VOCs Detectable Chemiresistor by Using Ligands Conjugated Molybdenum Disulfide (MoS2) |
| 초록 |
Two-dimensional (2D) layered materials have been favorably developed as gas sensor due to their high surface-to-volume ratio and excellent charge transport property. Among these candidates, molybdenum disulfide (MoS2) is one of the promising materials due to its superior properties as gas sensor as well as photodetector. In this study, we developed the MoS2 based chemiresistive gas sensor by forming the bulk film type of MoS2 layers. Especially, we conjugated thiolated ligands with the defects of sulfur vacancies on the MoS2 layers which were induced during exfoliation process that resulted in functionalized MoS2 sensing channels. The pristine and ligands conjugated MoS2 films showed unique sensing properties for representative VOCs (volatile organic compounds) which might lead to valuable and practical application in the breath analysis for lung cancer diagnosis. |
