In this study, N-methylpyrrolidone and acetonitrile, two common grinding solvents, were used during the liquid-phase exfoliation for the preparation of MoS2 nanosheets. The morphology and structure of MoS2 nanosheets were analyzed via scanning electron microscopy, X-ray diffraction, and Raman spectroscopy. The effects of grinding solvents on the gas-sensing performance of the MoS2 nanosheets were investigated for the first time. The results show that the sensitivities of MoS2 nanosheet exfoliation with N-methylpyrrolidone were 2.4-, 1.4-, 1.9-, and 2.7-fold higher than exfoliation with acetonitrile in the presence of formaldehyde, acetone, and ethanol and 98% relative humidity, respectively. MoS2 nanosheet exfoliation with N-methylpyrrolidone also has fast response and recovery characteristics to 50\u20131000 ppm of CH2O. Accordingly, although N-methylpyrrolidone cannot be removed completely from the surface of MoS2, it has good gas sensitivity compared with other samples. Therefore, N-methylpyrrolidone is preferred for the preparation of gas-sensitive MoS2 nanosheets in grinding-assisted liquid-phase exfoliation. The results provide an experimental basis for the preparation of two-dimensional materials and their application in gas sensors.<\/jats:p>","DOI":"10.3390\/nano12244485","type":"journal-article","created":{"date-parts":[[2022,12,19]],"date-time":"2022-12-19T07:59:21Z","timestamp":1671436761000},"page":"4485","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Effect of Different Solvents on Morphology and Gas-Sensitive Properties of Grinding-Assisted Liquid-Phase-Exfoliated MoS2 Nanosheets"],"prefix":"10.3390","volume":"12","author":[{"given":"Hao","family":"Wang","sequence":"first","affiliation":[{"name":"Key Laboratory of New Energy and Materials Research, Xinjiang Institute of Engineering, Urumqi 830023, China"},{"name":"Xinjiang Condensed Matter Phase Transition and Microstructure Laboratory, College of Physics Science and Technology, Yili Normal University, Yining 835000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaojie","family":"Xu","sequence":"additional","affiliation":[{"name":"Key Laboratory of New Energy and Materials Research, Xinjiang Institute of Engineering, Urumqi 830023, China"},{"name":"Xinjiang Condensed Matter Phase Transition and Microstructure Laboratory, College of Physics Science and Technology, Yili Normal University, Yining 835000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4855-2651","authenticated-orcid":false,"given":"Talgar","family":"Shaymurat","sequence":"additional","affiliation":[{"name":"Key Laboratory of New Energy and Materials Research, Xinjiang Institute of Engineering, Urumqi 830023, China"},{"name":"Xinjiang Condensed Matter Phase Transition and Microstructure Laboratory, College of Physics Science and Technology, Yili Normal University, Yining 835000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"044030","DOI":"10.1103\/PhysRevApplied.7.044030","article-title":"Model for the Operation of a Monolayer MoS2 Thin-Film Transistor with Charges Trapped near the Channel Interface","volume":"7","author":"Hur","year":"2017","journal-title":"Phys.
