This high-performance gas sensor is based on MOF-5 microparticles embedded on a conductivity-controlled chitosan (CS) organic membrane. The conductivity of the organic membrane is controlled by blending it with a glycerol ionic liquid (IL) at different concentrations. The sensor showed a remarkable detection sensitivity for H2S gas at a concentrations level as low as 1 ppm at room temperature. The MOF-5\/CS\/IL gas sensor demonstrates a highly desirable detection selectivity, fast response time (&amp;lt;8 s), recovery time of less than 30 s, and outstanding sensing stability averaging at 97% detection with 50 ppm of H2S gas. This composite having high sensitivity, low-power consumption, and flexibility holds great promise for addressing current challenges pertinent to environmental sustainability.<\/jats:p>","DOI":"10.1021\/acsomega.1c02295","type":"journal-article","created":{"date-parts":[[2021,6,30]],"date-time":"2021-06-30T05:47:06Z","timestamp":1625032026000},"page":"17690-17697","source":"Crossref","is-referenced-by-count":98,"title":["A Highly Sensitive and Flexible Metal\u2013Organic\nFramework Polymer-Based H2S Gas Sensor"],"prefix":"10.1021","volume":"6","author":[{"given":"Ashraf","family":"Ali","sequence":"first","affiliation":[{"name":"United Arab Emirates University , , ,","place":["Al-Ain, United Arab Emirates, 15551"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7586-9785","authenticated-orcid":true,"given":"Ahmed","family":"Alzamly","sequence":"additional","affiliation":[{"name":"United Arab Emirates University , , ,","place":["Al-Ain, United Arab Emirates, 15551"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaser E","family":"Greish","sequence":"additional","affiliation":[{"name":"United Arab Emirates University , , ,","place":["Al-Ain, United Arab Emirates, 15551"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maram","family":"Bakiro","sequence":"additional","affiliation":[{"name":"United Arab Emirates University , , ,","place":["Al-Ain, United Arab Emirates, 15551"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4977-925X","authenticated-orcid":true,"given":"Ha L.","family":"Nguyen","sequence":"additional","affiliation":[{"name":"United Arab Emirates University , , ,","place":["Al-Ain, United Arab Emirates, 15551"]},{"name":"Berkeley Global Science Institute , , ,","place":["Berkeley, California, United States, 94720"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9232-172X","authenticated-orcid":true,"given":"Saleh T.","family":"Mahmoud","sequence":"additional","affiliation":[{"name":"United Arab Emirates University , , ,","place":["Al-Ain, United Arab Emirates, 15551"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2021,6,30]]},"reference":[{"key":"2026081711241008600_cit1","doi-asserted-by":"publisher","first-page":"202","DOI":"10.1021\/ed082p202","article-title":"Hydrogen\nSulfide","volume":"82","author":"Young","year":"2005","journal-title":"J.
