In this work we have studied the influence on the gas-sensitive properties of nanocrystalline zinc oxide synthesized by atmospheric pressure solvothermal synthesis, with the addition of 1\u20135% of multilayer two-dimensional titanium carbide Ti2CTx, obtained by etching Ti2AlC with NaF solution in hydrochloric acid. It was found that all the obtained materials have high sensitivity and selectivity with respect to 4\u201320 ppm NO2 at a detection temperature of 200 \u00b0C. It is shown that the selectivity towards this compound is best for the sample containing the highest amount of Ti2CTx dopant. It has been found that as the MXene content increases, there is an increase in nitrogen dioxide (4 ppm) from 1.6 (ZnO) to 20.5 (ZnO-5 mol% Ti2CTx). reactions which the responses to nitrogen dioxide increase. This may be due to the increase in the specific surface area of the receptor layers, the presence of MXene surface functional groups, as well as the formation of the Schottky barrier at the interface between the phases of the components.<\/jats:p>","DOI":"10.3390\/mi14040725","type":"journal-article","created":{"date-parts":[[2023,3,24]],"date-time":"2023-03-24T09:26:21Z","timestamp":1679649981000},"page":"725","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Gas-Sensitive Properties of ZnO\/Ti2CTx Nanocomposites"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8112-1821","authenticated-orcid":false,"given":"Elizaveta P.","family":"Simonenko","sequence":"first","affiliation":[{"name":"Kurnakov Institute of General and Inorganic Chemistry, Russian Academy of Sciences, Moscow 119991, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0127-4153","authenticated-orcid":false,"given":"Ilya A.","family":"Nagornov","sequence":"additional","affiliation":[{"name":"Kurnakov Institute of General and Inorganic Chemistry, Russian Academy of Sciences, Moscow 119991, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4865-3054","authenticated-orcid":false,"given":"Artem S.","family":"Mokrushin","sequence":"additional","affiliation":[{"name":"Kurnakov Institute of General and Inorganic Chemistry, Russian Academy of Sciences, Moscow 119991, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksey A.","family":"Averin","sequence":"additional","affiliation":[{"name":"Frumkin Institute of Physical Chemistry and Electrochemistry, Russian Academy of Sciences, Moscow 199071, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yulia M.","family":"Gorban","sequence":"additional","affiliation":[{"name":"Kurnakov Institute of General and Inorganic Chemistry, Russian Academy of Sciences, Moscow 119991, Russia"},{"name":"Mendeleev University of Chemical Technology of Russia, Moscow 125047, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8130-8503","authenticated-orcid":false,"given":"Tatiana L.","family":"Simonenko","sequence":"additional","affiliation":[{"name":"Kurnakov Institute of General and Inorganic Chemistry, Russian Academy of Sciences, Moscow 119991, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4209-6034","authenticated-orcid":false,"given":"Nikolay P.","family":"Simonenko","sequence":"additional","affiliation":[{"name":"Kurnakov Institute of General and Inorganic Chemistry, Russian Academy of Sciences, Moscow 119991, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikolay T.","family":"Kuznetsov","sequence":"additional","affiliation":[{"name":"Kurnakov Institute of General and Inorganic Chemistry, Russian Academy of Sciences, Moscow 119991, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"100116","DOI":"10.1016\/j.sintl.2021.100116","article-title":"A review on environmental gas sensors: Materials and technologies","volume":"2","author":"Dhall","year":"2021","journal-title":"Sens.
