Hybrid SnS2-SnO2−x flaked nanostructures were obtained from 2D-SnS2 flakes deposited as a thin sensing film onto a conductometric transducing platform and annealed in air. The formation of 2D-SnS2/SnO2−x mixed phases and the materials morphologies were investigated by in situ Micro-Raman spectroscopy and SEM-EDX analysis. As annealing temperature of the sensitive film increases, the response towards ammonia increases showing a maximum at 250 °C. This behavior can be explained on the basis of the morphological modification and the formation of mixed phases.

Abstract
Hybrid SnS2-SnO2−x flaked nanostructures were obtained from 2D-SnS2 flakes deposited as a thin sensing film onto a conductometric transducing platform and annealed in air. The formation of 2D-SnS2/SnO2−x mixed phases and the materials morphologies were investigated by in situ Micro-Raman spectroscopy and SEM-EDX analysis. As annealing temperature of the sensitive film increases, the response towards ammonia increases showing a maximum at 250 °C. This behavior can be explained on the basis of the morphological modification and the formation of mixed phases.File in questo prodotto:
