Undoped and Sb-doped SnO_2 nanofibers were prepared by electrospinning and their responses to H_2, CO, CH_4, C_3H_8, and C_2H_5OH were measured. In the undoped SnO_2 nanofibers, the gas response (R_a/R_g, R_a: resistance in air, R_g: resistance in gas) to 100 ppm C_2H_5OH was very high(33.9), while that to the other gases ranged from 1.6 to 2.2. By doping with 2.65 wt% Sb, the response to 100 ppm C_2H_5OH was decreased to 4.5, whereas the response to H_2 was increased to 3.0. This demonstrates the possibility of detecting a high H_2 concentration with minimum interference from C_2H_5OH and the potential to control the gas selectivity by Sb doping.
