SnO₂ nanofibers were fabricated by electrospinning, using SnCl₂ ·2H₂O as the raw material. The influences of ZnO doping on the morphologies, structures, and compositions of the SnO₂ nanofibers were studied by introducing different amounts of ZnO into the SnO₂. The crystallography and microstructures of the synthesized SnO₂/ZnO composite nanofibers with different molar ratios of Sn to Zn were investigated using thermogravimetric/differential thermal analysis (TG-DTA), X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and energy dispersive X-ray (EDX) spectroscopy. The obtained SnO₂/ZnO composite nanofibers with different ZnO contents had hollow hierarchical structures composed of nanocrystals. Different amounts of ZnO gave different structures. The characterization results showed that the introduction of ZnO into SnO₂ played an important role in the SnO₂ nanofiber structure. The gas sensing properties of sensors based on different ZnO-doped SnO₂ nanofibers were tested. The results indicated that the methanol-sensing performance of the sensor containing SnO₂/ZnO in a molar ratio of 1:1 was better than those of the others. The sensing mechanisms of ZnO-doped SnO₂ nanofibers were examined in detail. Possible reasons for the enhanced SnO₂ nanofibers were fabricated by electrospinning, using SnCl₂ ?2H₂O as the raw material.
