Abstract

In this work, the Staphylococcus aureus (S. aureus) was firstly used as a template coupled with PVP in electrospinning experiments, Sn2+ bonded with S. aureus and PVP to form nanofiber through electrospinning. Finally, we got the hierarchical mesoporous SnO2 nanotube after calcination of the nanofiber. The hierarchical mesoporous SnO2 nanotube as a gas sensor toward triethylamine (TEA) shows high sensitivity, better cycling stability and selectivity. The response and recovery time of the hierarchical mesoporous SnO2 nanotube to 10 ppm TEA are about 19 s and 10 s.
