Constructed heterostructured SnS@MoO3 hollow nanotubes and detected sensing properties towards TEA

To overcome the obstacle of triangular prism-like MoO3 nanorods (MoO3) gas sensor including low response, poor selectivity and a heavy influence of humidity to Triethylamine (TEA), heterostructured tin sulfide (SnS) composited with MoO3 hollow nanotubes ([email protected]3) were synthesised by a facilely hydrothermal method. Its morphology and structure were charactered through different technologies. The result indicated that the sensor based on [email protected]3 exhibited higher response (73.46%), shorter response/recovery time (8.1/4.5 s), excellently selectivity and anti-humidity properties than MoO3 to 50 ppm TEA at 250 °C. Thus, the [email protected]3 is a promising material for detecting TEA.
