文摘

Nanosized tin disulfide (SnS₂) powder was synthesized through a simple and inexpensive process, then characterized via thermal, chemical, structural and morphological analyses. Conductometric gas sensors based on thick films of synthesized SnS₂ were fabricated by means of screen-printing technology and their sensing properties tested vs. aldehydes, ketones and other gaseous compounds. We found that, at working temperature of 300 °C, the SnS₂ films showed a strong selectivity vs. the carbonyl group of aldehydes and ketones, proving that they can efficiently be detected even in complex mixtures with interferers. In comparison with its oxide counterpart, SnS₂ proved to be more stable, in term of the long-term drift of the signal. On the base of the obtained results, practical applications of such a sensor have been addressed.
