The pure and Ag-doped ZnO-SnO2 hollow nanofibers had been synthesized via electrospinning method. The structure and morphology of the nanofibers were characterized by various techniques. The as-prepared products combined the two large advantages in morphology: surface roughness and porosity. Moreover, the sensor based on the Ag-doped ZnO-SnO2 hollow nanofibers exhibited excellent gas sensing performance at the low operating temperature of 200 degrees C and the fast response and recovery characteristics at a low concentration (1 ppm). It presented good selectivity and high response toward ethanol compared to pure nanofibers. The results demonstrated that Ag-doped ZnO-SnO2 nanofibers could be used as a kind of promising material for selective detection of low-concentration ethanol gas. (C) 2017 Elsevier B.V.
