This study explores the acetone gas-sensing characteristics of the WS2 nanorod sensor for 5, 10, and 15 ppm concentrations at 25 \u00b0C, 50 \u00b0C, 75 \u00b0C, and 100 \u00b0C. The WS2 nanorod sensor shows the highest sensitivity of 94.5% at 100 \u00b0C for the 15 ppm acetone concentration. The WS2 nanorod sensor also reveals the outstanding selectivity of acetone compared to other gases, such as ammonia, ethanol, acetaldehyde, methanol, and xylene at 100 \u00b0C with a 15 ppm concentration. The estimated selectivity coefficient indicates that the selectivity of the WS2 nanorod acetone sensor is 7.1, 4.5, 3.7, 2.9, and 2.0 times higher than xylene, acetaldehyde, ammonia, methanol, and ethanol, respectively. In addition, the WS2 nanorod sensor also divulges remarkable stability of 98.5% during the 20 days of study. Therefore, it is concluded that the WS2 nanorod can be an excellent nanomaterial for developing acetone sensors for monitoring work\/public places.<\/jats:p>","DOI":"10.3390\/s22228609","type":"journal-article","created":{"date-parts":[[2022,11,8]],"date-time":"2022-11-08T09:02:42Z","timestamp":1667898162000},"page":"8609","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["WS2 Nanorod as a Remarkable Acetone Sensor for Monitoring Work\/Public Places"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9634-354X","authenticated-orcid":false,"given":"Rajneesh Kumar","family":"Mishra","sequence":"first","affiliation":[{"name":"Department of Physics, Yeungnam University, Gyeongsan 38541, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vipin","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Physics, Yeungnam University, Gyeongsan 38541, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1282-1709","authenticated-orcid":false,"given":"Le Gia","family":"Trung","sequence":"additional","affiliation":[{"name":"Department of Physics, Yeungnam University, Gyeongsan 38541, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gyu Jin","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Physics, Yeungnam University, Gyeongsan 38541, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeong Won","family":"Ryu","sequence":"additional","affiliation":[{"name":"Department of Physics, Yeungnam University, Gyeongsan 38541, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6087-6077","authenticated-orcid":false,"given":"Sagar M.","family":"Mane","sequence":"additional","affiliation":[{"name":"Division of Electronics and Electrical Engineering, Seoul Campus, Dongguk University, Seoul 04620, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae Cheol","family":"Shin","sequence":"additional","affiliation":[{"name":"Division of Electronics and Electrical Engineering, Seoul Campus, Dongguk University, Seoul 04620, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pushpendra","family":"Kumar","sequence":"additional","affiliation":[{"name":"Department of Physics, Manipal University Jaipur, Jaipur 303007, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung Hee","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Nanoconvergence Engineering, Jeonbuk National University, Jeonju 54896, Korea"},{"name":"Department of Polymer Nano-Science and Technology, Jeonbuk National University, Jeonju 54896, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin Seog","family":"Gwag","sequence":"additional","affiliation":[{"name":"Department of Physics, Yeungnam University, Gyeongsan 38541, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"28419","DOI":"10.1016\/j.ceramint.2022.06.155","article-title":"Facile synthesis of hierarchical Co3O4\/MWCNT composites with enhanced acetone sensing property","volume":"48","author":"Fu","year":"2022","journal-title":"Ceram.
