On the other hand, conventional high\u2212temperature gas detectors are unsuitable for safely detecting harmful gases at high activation temperatures. Photo\u2212activated gas detectors improve gas sensing performance at room temperature and enable low\u2212power operation. This review presents a timely overview of photo\u2212activated gas detectors that use illuminated light instead of thermal energy. Illuminated light assists in gas detection and is classified as visible or ultraviolet light. The research on photo\u2212activated gas detectors is organized according to the type of gas that can be intensively detected. In addition, a development strategy for advancing photo\u2212activated gas detectors is discussed.<\/jats:p>","DOI":"10.3390\/s22239228","type":"journal-article","created":{"date-parts":[[2022,11,28]],"date-time":"2022-11-28T08:13:09Z","timestamp":1669623189000},"page":"9228","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Recent Advances in Photo\u2212Activated Chemical Sensors"],"prefix":"10.3390","volume":"22","author":[{"given":"Dong Hyun","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, Gachon University, 1342 Seongnam\u2212daero, Seongnam 13120, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0772-3327","authenticated-orcid":false,"given":"Hocheon","family":"Yoo","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, Gachon University, 1342 Seongnam\u2212daero, Seongnam 13120, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"382","DOI":"10.1039\/b9nr00015a","article-title":"Nanostructured Pt decorated graphene and multi walled carbon nanotube based room temperature hydrogen gas sensor","volume":"1","author":"Kaniyoor","year":"2009","journal-title":"Nanoscale"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2220","DOI":"10.1016\/j.mee.2008.06.021","article-title":"Novel hydrogen gas sensor based on single ZnO nanorod","volume":"85","author":"Lupan","year":"2008","journal-title":"Microelectron.
