Therefore, investigating gas sensors operating at room temperature holds significant practical importance. In this study, coal-based porous carbon (C-700) and coal-based C\/MoO2 nanohybrid materials were synthesized using a simple one-step vapor deposition and sintering method, and their gas-sensing performance was investigated. The gas-sensing performance for several VOC gases (phenol, ethyl acetate, ethanol, acetone, triethylamine, and toluene) and a 95% RH high-humidity environment were tested. The results indicated that the C\/MoO2-450 sample sintered at 450 \u00b0C exhibited excellent specific selectivity towards acetone at room temperature, with a response value of 4153.09% and response\/recovery times of 10.8 s and 2.9 s, respectively. Furthermore, the C\/MoO2-450 sample also demonstrated good repeatability and long-term stability. The sensing mechanism of the synthesized materials was also explored. The superior gas-sensing performance can be attributed to the synergistic effect between the porous carbon and MoO2 nanoparticles. Given the importance of enhancing the high-tech and high-value-added utilization of coal, this study provides a viable approach for utilizing coal-based carbon materials in detecting volatile organic compounds at room temperature.<\/jats:p>","DOI":"10.3390\/s24134320","type":"journal-article","created":{"date-parts":[[2024,7,3]],"date-time":"2024-07-03T06:04:18Z","timestamp":1719986658000},"page":"4320","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Highly Selective Acetone Sensor Based on Coal-Based Carbon\/MoO2 Nanohybrid Material"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7400-6796","authenticated-orcid":false,"given":"Min","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Physics Science and Technology, Xinjiang University, Urumqi 830046, China"}]},{"given":"Yi","family":"Han","sequence":"additional","affiliation":[{"name":"School of Physics Science and Technology, Xinjiang University, Urumqi 830046, China"}]},{"given":"Ting","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Chemistry, Xinjiang University, Urumqi 830046, China"}]},{"given":"Hongguang","family":"Jia","sequence":"additional","affiliation":[{"name":"School of Physics Science and Technology, Xinjiang University, Urumqi 830046, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"128","DOI":"10.1007\/s10854-022-09566-y","article-title":"Highly sensitive and fast response acetone gas sensor based on Co3O4\u2013ZnO heterojunction assembled by porous nanoflowers","volume":"34","author":"Cheng","year":"2023","journal-title":"J.
