摘要
The in-situ Raman spectroscopy oxidation of the accordion-like V2CTx MXene has been studied. It was found that a nanocomposite of V2CTx/V3O7 composition was formed as a result. The elemental and phase composition, the microstructure of the synthesized V2CTx powder and MXene film as well as the V2CTx/V3O7 nanocomposite obtained at a minimum oxidation temperature of 250 °C were studied using a variety of physical and chemical analysis methods. It was found that the obtained V2CTx and V2CTx/V3O7 films have an increased sensitivity to ammonia and nitrogen dioxide, respectively, at room temperature and zero humidity. It was shown that the V2CTx/V3O7 composite material is characterized by an increase in the response value for a number of analytes (including humidity) by more than one order of magnitude, as well as a change in their detection mechanisms compared to the individual V2CTx MXene.
