WO_3-x/WS₂ Nanocomposites for Fast-Response Room Temperature Gas Sensing.

ABSTRACT: Currently, semiconductor gas sensors are being actively studied and used in various fields, including ecology, industry, and medical diagnostics. One of the major challenges is to reduce their operating temperature to room temperature. To address this issue, sensor layers based on WO_3-x/WS₂ nanostructures synthesized by the hydrothermal method have been proposed. In this paper, the morphology of the material's surface and its elemental composition were investigated, as well as the optical band gap. Additionally, changes in the resistance of the WO_3-x/WS₂ sensor layers under the influence of alcohol vapors at room temperature were analyzed. The results showed that the layers exhibited a significant response, with short response and recovery times.
