Electrospun ZnO Nanowires as Gas Sensors for propanol Detection

摘要：

　　We used an electrospinning method to produce ZnO nanofibers for propanol sensing.ZnO nanofibers were electrospun from a solution containing poly(4-vinyl phenol) (PVP) and zinc acetate.The morphology and structure of the as-prepared ZnO nanofibers have been characterized by scanning electron microscopy and X-ray diffraction,respectively.The calcination process of the ZnO/PVP composite nanofibers brought forth polycrystalline würtzite ZnO nanofibers with diameters of 50-70 nm.Under the optimized experimental conditions,the prepared product shows the desirable sensing characteristics towards propanol at 400°C.The high sensitivity,reversible response and good selectivity indicated its potential application as a chemical sensor.
