Fluorescence detection and resistive sensing are effective methods for detecting pollutants. Here, In-doped interpenetrating twin ZIF-8 and its annealed derivatives have been successfully designed and prepared as a multifunctional TEA sensor. On the one hand, ZIF-8-In exhibits excellent fluorescence emission enhancement at 450 nm in a dose-dependent manner to TEA in water within the concentration range of 1\u2013100 ppm, with a detection limit as low as 1 ppm. On the other hand, the annealed ZIF-8-In derivative is ZnO\/In2O3 with a porous hierarchical structure, which is a perfect sensitive material for manufacturing gas sensors. Within the concentration range of 1\u2013100 ppm, the ZnO\/In2O3 gas sensor has a high response for 100 ppm TEA, reaching 107.7 (Ra\/Rg), and can detect TEA gas as low as 1 ppm. Furthermore, the response of ZnO\/In2O3 sensors to TEA is at least 10 times that of the other four VOC gases, demonstrating excellent gas selectivity. This multifunctional sensor can adapt to complex detection situations, demonstrating good application prospects.<\/jats:p>","DOI":"10.3390\/s24165425","type":"journal-article","created":{"date-parts":[[2024,8,23]],"date-time":"2024-08-23T12:58:07Z","timestamp":1724417887000},"page":"5425","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["ZIF-8-Derived Multifunctional Triethylamine Sensor"],"prefix":"10.3390","volume":"24","author":[{"given":"Shuo","family":"Xiao","sequence":"first","affiliation":[{"name":"School of Environmental and Chemical Engineering, Shanghai University, Shanghai 200444, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zheng","family":"Jiao","sequence":"additional","affiliation":[{"name":"School of Environmental and Chemical Engineering, Shanghai University, Shanghai 200444, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4858-2743","authenticated-orcid":false,"given":"Xuechun","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Environmental and Chemical Engineering, Shanghai University, Shanghai 200444, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"352","DOI":"10.1016\/j.jhazmat.2019.02.098","article-title":"Rational shape control of porous Co3O4 assemblies derived from MOF and their structural effects on n-butanol sensing","volume":"371","author":"Wang","year":"2019","journal-title":"J.
