IrOx nanoparticles were synthetized using a two-step method, based on a hydrolysis and acid condensation growth mechanism. The metal oxide nanoparticles obtained were employed for decorating the sidewalls of carbon nanotubes. Iridium-oxide nanoparticle decorated carbon nanotube material showed higher and more stable responses towards NH3 and NO2 than bare carbon nanotubes under different experimental conditions, establishing the optimal operating temperatures and estimating the limits of detection and quantification. Furthermore, the nanomaterials employed were studied using different morphological and compositional characterization techniques and a gas sensing mechanism is proposed.<\/jats:p>","DOI":"10.3390\/s19010113","type":"journal-article","created":{"date-parts":[[2018,12,31]],"date-time":"2018-12-31T07:22:30Z","timestamp":1546240950000},"page":"113","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Gas Sensing with Iridium Oxide Nanoparticle Decorated Carbon Nanotubes"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3508-3462","authenticated-orcid":false,"given":"Juan","family":"Casanova-Ch\u00e1fer","sequence":"first","affiliation":[{"name":"MINOS-EMaS, Universitat Rovira i Virgili, 43007 Tarragona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7005-220X","authenticated-orcid":false,"given":"Eric","family":"Navarrete","sequence":"additional","affiliation":[{"name":"MINOS-EMaS, Universitat Rovira i Virgili, 43007 Tarragona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xavier","family":"Noirfalise","sequence":"additional","affiliation":[{"name":"Materia Nova, 7000 Mons, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Polona","family":"Umek","sequence":"additional","affiliation":[{"name":"Jo\u017eef Stefan Institute, 10000 Ljubljana, Slovenia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3330-6693","authenticated-orcid":false,"given":"Carla","family":"Bittencourt","sequence":"additional","affiliation":[{"name":"ChIPS, University of Mons, 7000 Mons, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6164-4342","authenticated-orcid":false,"given":"Eduard","family":"Llobet","sequence":"additional","affiliation":[{"name":"MINOS-EMaS, Universitat Rovira i Virgili, 43007 Tarragona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1016\/j.snb.2012.11.014","article-title":"Gas sensors using carbon nanomaterials: A review","volume":"179","author":"Llobet","year":"2013","journal-title":"Sens.
