摘要
Developing high-performance n-butanol gas sensors is of great significance for environmental protection and human health. The Bi-doped ZnFe2O4 nanofibers exhibit promising potential as a viable option for n-butanol sensors. In this study, a series of high response and fast response n-butanol gas sensors were successfully fabricated by Bi-doped ZnFe2O4 nanofibers with different atomic percentages (0 %, 1 %, 3 %, 5 %), which were synthesized by a facile electrospinning method. The nanofibers with a Bi/Zn molar ratio of 3 % showed a response value of 23.6 to 100 ppm n-butanol at 175 °C, which was 2.4 times higher than that of the pure ZnFe2O4 nanofibers, and with a lower concentration detection limit (1.5 for 100 ppb n-butanol). In addition, the gas sensing materials had a good selectivity and long-term stability to n-butanol, and the mechanism of the good sensing performance of Bi doped ZnFe2O4 nanofibers for n-butanol is also analyzed in this paper.
