In this work we analyzed the influence of relative humidity on sensor properties of the hybrid materials based on the nanocrystalline SnO2 and In2O3 and Ru (II) heterocyclic complex and verified the possibility of using such materials for NO (0.25\u20134.0 ppm) and NO2 (0.05\u20131.0 ppm) detection in high humidity conditions (relative humidity (RH) = 20%, 40%, 65%, 90%) at room temperature during periodic blue (\u03bbmax = 470 nm) illumination. To reveal the reasons for the different influence of humidity on the sensors\u2019 sensitivity when detecting NO and NO2, electron paramagnetic resonance (EPR) spectroscopy and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) investigations were undertaken. It was established that the substitution of adsorbed oxygen by water molecules causes the decrease in sensor response to NO in humid air. The influence of humidity on the interaction of sensitive materials with NO2 is determined by the following factors: the increase in charge carrier\u2019s concentration, the decrease in the number of active sites capable of interacting with gases, and possible substitution of chemisorbed oxygen with NO2\u2212 groups.<\/jats:p>","DOI":"10.3390\/nano10050915","type":"journal-article","created":{"date-parts":[[2020,5,11]],"date-time":"2020-05-11T10:01:18Z","timestamp":1589191278000},"page":"915","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":50,"title":["Effect of Humidity on Light-Activated NO and NO2 Gas Sensing by Hybrid Materials"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5133-4009","authenticated-orcid":false,"given":"Abulkosim","family":"Nasriddinov","sequence":"first","affiliation":[{"name":"Chemistry Department, Moscow State University, 119991 Moscow, Russia"},{"name":"Faculty of Materials Science, Moscow State University, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3354-0885","authenticated-orcid":false,"given":"Marina","family":"Rumyantseva","sequence":"additional","affiliation":[{"name":"Chemistry Department, Moscow State University, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4542-6999","authenticated-orcid":false,"given":"Elizaveta","family":"Konstantinova","sequence":"additional","affiliation":[{"name":"Physics Department, Moscow State University, 119991 Moscow, Russia"},{"name":"Faculty of nano-, bio-, information and cognitive technologies, Moscow Institute of Physics and Technology, Dolgoprudny, 141700 Moscow Region, Russia"},{"name":"National Research Center \u201cKurchatov Institute\u201d, 123182 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2894-501X","authenticated-orcid":false,"given":"Artem","family":"Marikutsa","sequence":"additional","affiliation":[{"name":"Chemistry Department, Moscow State University, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergey","family":"Tokarev","sequence":"additional","affiliation":[{"name":"Chemistry Department, Moscow State University, 119991 Moscow, Russia"},{"name":"A.N.
