In particular, the possibility of operating at room temperature (RT) is desirable for 2D gas sensors because it significantly reduces the power consumption of the sensing device. Furthermore, RT gas sensors are among the first choices for the development of flexible and wearable devices. In this review, we focus on the 2D MXenes used for the realization of RT gas sensors. Hence, pristine, doped, decorated, and composites of MXenes with other semiconductors for gas sensing are discussed. Two-dimensional MXene nanomaterials are discussed, with greater emphasis on the sensing mechanism. MXenes with the ability to work at RT have great potential for practical applications such as flexible and\/or wearable gas sensors.<\/jats:p>","DOI":"10.3390\/s23218829","type":"journal-article","created":{"date-parts":[[2023,10,30]],"date-time":"2023-10-30T13:26:55Z","timestamp":1698672415000},"page":"8829","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Room Temperature Chemiresistive Gas Sensors Based on 2D MXenes"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2301-634X","authenticated-orcid":false,"given":"Ali","family":"Mirzaei","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, Shiraz University of Technology, Shiraz 71557-13876, Iran"}]},{"given":"Myoung Hoon","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Inha University, Incheon 22212, Republic of Korea"}]},{"given":"Haniyeh","family":"Safaeian","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Shiraz University of Technology, Shiraz 71557-13876, Iran"}]},{"given":"Tae-Un","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Inha University, Incheon 22212, Republic of Korea"}]},{"given":"Jin-Young","family":"Kim","sequence":"additional","affiliation":[{"name":"The Research Institute of Industrial Science, Hanyang University, Seoul 04763, Republic of Korea"}]},{"given":"Hyoun Woo","family":"Kim","sequence":"additional","affiliation":[{"name":"The Research Institute of Industrial Science, Hanyang University, Seoul 04763, Republic of Korea"},{"name":"Division of Materials Science and Engineering, Hanyang University, Seoul 04763, Republic of Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6912-3509","authenticated-orcid":false,"given":"Sang Sub","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Inha University, Incheon 22212, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"241102","DOI":"10.1063\/1.5118805","article-title":"Resistive gas sensors based on metal-oxide nanowires","volume":"126","author":"Mirzaei","year":"2019","journal-title":"J.
