In this work, hybrids of semiconductor nanomaterials based on TiO2 and ZnO were prepared by laser ablation of Zn and Ti plates in water and then tested as chemiresistive gas sensors towards volatile organics (2-propanol, acetaldehyde, ethanol, methanol) and ammonia. An infrared millisecond pulsed laser with energy 2.0 J\/pulse and a repetition rate of 5 Hz was applied to Zn and Ti metal targets in different ablation sequences to produce two nano-hybrids (TiO2\/ZnO and ZnO\/TiO2). The surface chemistry, morphology, crystallinity, and phase composition of the prepared hybrids were found to tune their gas-sensing properties. Among all tested gases, sample TiO2\/ZnO showed selectivity to ethanol, while sample ZnO\/TiO2 sensed 2-propanol at room temperature, both with a detection limit of ~50 ppm. The response and recovery times were found to be 24 and 607 s for the TiO2\/ZnO sensor, and 54 and 50 s for its ZnO\/TiO2 counterpart, respectively, towards 100 ppm of the target gas at room temperature.<\/jats:p>","DOI":"10.3390\/nano13040670","type":"journal-article","created":{"date-parts":[[2023,2,9]],"date-time":"2023-02-09T02:55:54Z","timestamp":1675911354000},"page":"670","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Gas Sensing of Laser-Produced Hybrid TiO2-ZnO Nanomaterials under Room-Temperature Conditions"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5541-1884","authenticated-orcid":false,"given":"Neli","family":"Mintcheva","sequence":"first","affiliation":[{"name":"Research Institute of Science and Technology, Tokai University, Hiratsuka 259-1292, Kanagawa, Japan"},{"name":"Department of Chemistry, University of Mining and Geology, 1700 Sofia, Bulgaria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5399-4967","authenticated-orcid":false,"given":"Dinesh Kumar","family":"Subbiah","sequence":"additional","affiliation":[{"name":"Centre for Nanotechnology & Advanced Biomaterials (CeNTAB), School of Electrical & Electronics Engineering, SASTRA Deemed University, Thanjavur 613 401, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marat E.","family":"Turabayev","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Tokai University, Hiratsuka 259-1292, Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stanislav O.","family":"Gurbatov","sequence":"additional","affiliation":[{"name":"Far Eastern Federal University, 690041 Vladivostok, Russia"},{"name":"Institute of Automation and Control Processes, Far Eastern Branch of the Russian Academy of Science, 690091 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John Bosco Balaguru","family":"Rayappan","sequence":"additional","affiliation":[{"name":"Centre for Nanotechnology & Advanced Biomaterials (CeNTAB), School of Electrical & Electronics Engineering, SASTRA Deemed University, Thanjavur 613 401, Tamil Nadu, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandr A.","family":"Kuchmizhak","sequence":"additional","affiliation":[{"name":"Far Eastern Federal University, 690041 Vladivostok, Russia"},{"name":"Institute of Automation and Control Processes, Far Eastern Branch of the Russian Academy of Science, 690091 Vladivostok, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1365-9221","authenticated-orcid":false,"given":"Sergei A.","family":"Kulinich","sequence":"additional","affiliation":[{"name":"Research Institute of Science and Technology, Tokai University, Hiratsuka 259-1292, Kanagawa, Japan"},{"name":"Department of Mechanical Engineering, Tokai University, Hiratsuka 259-1292, Kanagawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"80","DOI":"10.14356\/kona.2017009","article-title":"Synthesis of nanoparticles by laser ablation: A review","volume":"34","author":"Kim","year":"2017","journal-title":"KONA Powder Part.
