Therefore, it is necessary to develop a sensor for the real-time detection of formaldehyde in low concentrations. According to the chemical interaction between amino groups and formaldehyde, a MIL-101(Cr) aminated-material-based formaldehyde cantilever sensor was prepared, of which ethylenediamine- functionalized MIL-101(Cr) named ED-MIL-101(Cr)) showed the best gas sensing performance. Using quasi-in situ infrared spectroscopy, ED-MIL-101(Cr) was found bound to formaldehyde through a Schiff base. The adsorption enthalpy of formaldehyde-bound ED-MIL-101(Cr) was \u221252.6 kJ\/mol, which corresponds to weak chemical adsorption, so the material showed good selectivity. In addition, ED-MIL-101(Cr) has the most active sites, so its response value to formaldehyde is larger and it takes longer to reach saturation adsorption than bare MIL-101(Cr). Through the research on the gas sensing performance of functionalized MIL-101(Cr) material, we found that it has a strong application potential in the field of formaldehyde monitoring, and the material performance can be quantitatively and accurately evaluated through combining calculation and experimentation for understanding the gas sensing mechanism.<\/jats:p>","DOI":"10.3390\/nano13142072","type":"journal-article","created":{"date-parts":[[2023,7,14]],"date-time":"2023-07-14T08:35:47Z","timestamp":1689323747000},"page":"2072","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Microgravimetric Modeling\u2014A New Method for Extracting Adsorption Parameters of Functionalized MIL-101(Cr)"],"prefix":"10.3390","volume":"13","author":[{"given":"Xu","family":"Zhang","sequence":"first","affiliation":[{"name":"NEST Laboratory, Department of Chemistry, College of Science, Shanghai University, Shanghai 200444, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Tian","sequence":"additional","affiliation":[{"name":"NEST Laboratory, Department of Chemistry, College of Science, Shanghai University, Shanghai 200444, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiheng","family":"Ma","sequence":"additional","affiliation":[{"name":"NEST Laboratory, Department of Chemistry, College of Science, Shanghai University, Shanghai 200444, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"He","family":"Wang","sequence":"additional","affiliation":[{"name":"NEST Laboratory, Department of Chemistry, College of Science, Shanghai University, Shanghai 200444, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhixuan","family":"Cheng","sequence":"additional","affiliation":[{"name":"NEST Laboratory, Department of Chemistry, College of Science, Shanghai University, Shanghai 200444, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4214-8532","authenticated-orcid":false,"given":"Jiaqiang","family":"Xu","sequence":"additional","affiliation":[{"name":"NEST Laboratory, Department of Chemistry, College of Science, Shanghai University, Shanghai 200444, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"126460","DOI":"10.1016\/j.jhazmat.2021.126460","article-title":"iHigh-performance and wearable hazardous gases sensor based on n-n heterojunction film of NGO and tetrakis (1\u2014pyrenyl) porphyrin","volume":"419","author":"Qi","year":"2021","journal-title":"J.
