Ammonia (NH3) gas is an important chemical in many industries. Employees working in such industrial areas may exposed to a certain concentration of NH3 which could cause various symptoms such as irritation of skin and eyes and problems in respiratory system. The development of new NH3 sensing material has attracted great attention. In this study, porous tin dioxide nanofibers (SnO2 NFs) were successfully fabricated by electrospinning. The SnO2 NFs was composited with polyaniline (PANI), conducting polymer. The tin dioxide nanofibers@polyaniline nanocomposite (SnO2 NFs@PANI) was examined and showed improving and desirable sensing for NH3 gas, which includes high sensitivity, quick response and fast recovery times at room temperature. HIGHLIGHTS Ammonia (NH3) gas has been used in many industries. For worker safety in those industrial area, a reliable NH3 gas sensor is necessary A new tin dioxide nanofibers@polyaniline nanocomposite (SnO2 NFs@PANI) had successfully developed for a selectively ammonia gas sensor Excellent analytical performance in team of stability, repeatability and widely response for NH3 concentration was achieved GRAPHICAL ABSTRACT
