The fabricated CeO<jats:sub>2<\/jats:sub> nanosheets (NSs) showed an optical band gap of 3.53 eV and cubic fluorite crystal structure with enriched defect states. The formation of 2D NSs with well crystalline phases is clearly observed from high-resolution transmission electron microscope (HRTEM) images. The NSs have been shown tremendous blue-green emission related to large oxygen defects. A VOC sensing device based on fabricated two-dimensional NSs has been developed for the sensing of different VOCs. The device showed better sensing for formaldehyde compared with other VOCs (2-propanol, methanol, ethanol, and toluene). The response was found to be 4.35, with the response and recovery time of 71 s and 310 s, respectively. The device showed an increment of the recovery time (71 s to 100 s) with the decrement of the formaldehyde ppm (100 ppm to 20 ppm). Theoretical fittings provided the detection limit of formaldehyde \u22488.86 \u00b1 0.45 ppm with sensitivity of 0.56 \u00b1 0.05 ppm<jats:sup>\u22121<\/jats:sup>. The sensor device showed good reproducibility with excellent stability over the study period of 135 d, with a deviation of 1.8% for 100 ppm formaldehyde. The average size of the NSs (\u224824 nm) calculated from HRTEM observation showed lower value than the calculated Debye length (\u224844 nm) of the charge accumulation during VOCs sensing. Different defect states, interstitial and surface states in the CeO<jats:sub>2<\/jats:sub> NSs as observed from the Raman spectrum and emission spectrum are responsible for the formaldehyde sensing. This work offers an insight into 2D semiconductor-based oxide material for highly sensitive and stable formaldehyde sensors.<\/jats:p>","DOI":"10.1088\/1361-6528\/ad6e8b","type":"journal-article","created":{"date-parts":[[2024,8,13]],"date-time":"2024-08-13T22:48:20Z","timestamp":1723589300000},"page":"455501","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["Emerging 2D nanoscale metal oxide sensor: semiconducting CeO<sub>2<\/sub> nano-sheets for enhanced formaldehyde vapor sensing"],"prefix":"10.1088","volume":"35","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7201-1687","authenticated-orcid":true,"given":"Amit Kumar","family":"Bhunia","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bidesh","family":"Mahata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Biswajit","family":"Mandal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2741-541X","authenticated-orcid":true,"given":"Prasanta Kumar","family":"Guha","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satyajit","family":"Saha","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2024,8,27]]},"reference":[{"key":"nanoad6e8bbib1","doi-asserted-by":"publisher","DOI":"10.1016\/j.snb.2023.134210","article-title":"Humidity-resistive ethanol gas sensor based on electrospun tungsten-doped cerium oxide hollow nanofibers","volume":"393","author":"Wang","year":"2023","journal-title":"Sens.
