description | In this work, a novel heterojunction based on ZnSnO<sub>3</sub>/ZnO nanofibers was prepared by a simple electrospinning method. The crystal, structural, and surface compositional properties of ZnSnO<sub>3</sub> and ZnSnO<sub>3</sub>/ZnO composite nanofibers were investigated by X-ray diffractometer (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray photoelectron spectrometer (XPS), and Brunauer–Emmett–Teller (BET). Compared to pure ZnSnO<sub>3</sub> nanofibers, the ZnSnO<sub>3</sub>/ZnO heterostructure nanofibers had high sensitivity and selectivity response with the fast response toward ethanol gas at low operational temperature. The sensing response of the sensor based on ZnSnO<sub>3</sub>/ZnO composite nanofibers was 19.6 toward 50 ppm ethanol gas at 225 °C, which was about 1.5 times superior to that of pure ZnSnO<sub>3</sub> nanofibers. It can be owed mainly to the oxygen vacancies and the synergistic effect between ZnSnO<sub>3</sub> and ZnO. |
