Synthesis of MoS2 Nanochains by Electrospinning for Ammonia Detection at Room Temperature

MoS2 nanochains were successfully prepared via facile electrospinning and a hydrothermal process. The morphology of MoS2 nanochains was evaluated by field emission scanning electron microscopy and high-resolution transmission electron microscopy. A slurry composed of the MoS2 nanochains was coated on a silver electrode to detect ammonia. The detection range of ammonia was between 25 and 500 ppm. MoS2 nanochains offered outstanding sensing response, repeatable reproducibility, and excellent selectivity with a detection limit of 720 ppb. The responsiveness of MoS2 nanochains to ammonia remained unchanged for 1 week.
