Owing to its unusual adsorptive properties, JUK-8 can be considered as a promising sensing material for construction of detectors of volatile organic compounds (VOCs) in air. Quasi-equilibrated temperature-programmed desorption and adsorption (QE-TPDA) is a versatile method dedicated to characterization of porous materials. In this work, QE-TPDA was employed to study co-adsorption of water and selected alcohols in JUK-8. For the first time an infrared detector sensitive to organic compounds was used in the QE-TPDA measurements, allowing the study of the influence of water vapor on sorption of VOCs. The QE-TPDA profiles of the studied alcohols, exhibiting two desorption maxima and two adsorption minima, are consistent with the standard sorption isotherms, revealing a two-step adsorption\u2013desorption mechanism. The profiles recorded in the presence of water are noticeably changed in different ways for different alcohols. While at low relative humidity (RH) (ca. 20%) the low temperature adsorption states of ethanol and 1-propanol were only slightly destabilized, for 2-propanol almost complete suppression of adsorption was observed. The results found for moderate RH levels (ca. 50%) indicated that the opening of the JUK-8 structure, responsible for its breathing behavior, was followed by the filling of the just generated pores with a water\u2013alcohol mixture.<\/jats:p>","DOI":"10.3390\/molecules29102309","type":"journal-article","created":{"date-parts":[[2024,5,14]],"date-time":"2024-05-14T10:26:36Z","timestamp":1715682396000},"page":"2309","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Co-Adsorption of Alcohols and Water in JUK-8 Studied Using Quasi-Equilibrated Thermodesorption"],"prefix":"10.3390","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4055-9664","authenticated-orcid":false,"given":"Wac\u0142aw","family":"Makowski","sequence":"first","affiliation":[{"name":"Faculty of Chemistry, Jagiellonian University in Krak\u00f3w, Gronostajowa 2, 30-387 Krak\u00f3w, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrycja","family":"Gryta","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Jagiellonian University in Krak\u00f3w, Gronostajowa 2, 30-387 Krak\u00f3w, Poland"},{"name":"Doctoral School of Exact and Natural Sciences, Jagiellonian University in Krak\u00f3w, \u0141ojasiewicza 11, 30-348 Krak\u00f3w, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8286-917X","authenticated-orcid":false,"given":"Gabriela","family":"Jajko","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Jagiellonian University in Krak\u00f3w, Gronostajowa 2, 30-387 Krak\u00f3w, Poland"},{"name":"Doctoral School of Exact and Natural Sciences, Jagiellonian University in Krak\u00f3w, \u0141ojasiewicza 11, 30-348 Krak\u00f3w, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-8774-2810","authenticated-orcid":false,"given":"Pattaraphon","family":"Rodlamul","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Jagiellonian University in Krak\u00f3w, Gronostajowa 2, 30-387 Krak\u00f3w, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1426-2477","authenticated-orcid":false,"given":"Damian","family":"J\u0119drzejowski","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Jagiellonian University in Krak\u00f3w, Gronostajowa 2, 30-387 Krak\u00f3w, Poland"},{"name":"Doctoral School of Exact and Natural Sciences, Jagiellonian University in Krak\u00f3w, \u0141ojasiewicza 11, 30-348 Krak\u00f3w, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kornel","family":"Roztocki","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Adam Mickiewicz University, Uniwersytetu Pozna\u0144skiego 8, 61-614 Pozna\u0144, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0064-5541","authenticated-orcid":false,"given":"Dariusz","family":"Matoga","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Jagiellonian University in Krak\u00f3w, Gronostajowa 2, 30-387 Krak\u00f3w, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5867","DOI":"10.1039\/C3CS60483G","article-title":"Metal-Organic Frameworks Based on Flexible Ligands (FL-MOFs): Structures and Applications","volume":"43","author":"Lin","year":"2014","journal-title":"Chem.
