In this work, we developed a NH3 gas sensor based on polyaniline (PANI) composited with MoS2 nanosheet-coated SnO2 nanotubes (PMS) via electrostatic spinning, hydrothermal route and in-situ polymerization technique. The morphologies, nanostructures and compositions of the materials were obtained from X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Field emission scanning electron microscopy (FESEM), Transmission electron microscope (TEM) and Brunauer-Emmett-Teller method (BET). Thanks to nanostructure and the synergistic properties of PANI and MoS2/SnO2, the designed PMS gas sensor exhibited response signal of 10.9 towards 100 ppm NH3 at room temperature and a low detection limit of 200 ppb with good response-recovery time, good repeatability, acceptable flexibility and excellent selectivity. This study offers a versatile platform to modify PANI for highly selective detection of NH3 gas sensor at room temperature.
