Nb2O5–TiO2 nanomaterials containing 0.5 and 10 mol % TiO2 have been synthesized by the programmed deposition method. The products have been characterized by modern physicochemical methods The Nb2O5–TiO2 nanomaterials have a crystal structure of orthorhombic Nb2O5 (T-phase). Individual niobium oxide is composed of nanoparticles with an average size of 15 ± 3 nm; increasing the TiO2 content entails microstructural changes. For the Nb2O5–TiO2 coatings, a set of chemoresistive gas-sensing properties has been studied. Of all the analyzed gases, the highest sensitivity was recorded for oxygen and hydrogen sulfide. It has been shown that the sample with 5% TiO2 is most sensitive to О2 and H2S, which is explained by the formation of additional oxygen vacancies. [ABSTRACT FROM AUTHOR] |
