Hierarchical mesoporous SnO2 nanotube templated by staphylococcus aureus through electrospinning for highly sensitive detection of triethylamine

In this work, the Staphylococcus aureus ( S. aureus ) was firstly used as a template coupled with PVP in electrospinning experiments, Sn 2+ bonded with S. aureus and PVP to form nanofiber through electrospinning. Finally, we got the hierarchical mesoporous SnO 2 nanotube after calcination of the nanofiber . The hierarchical mesoporous SnO 2 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 SnO 2 nanotube to 10 ppm TEA are about 19 s and 10 s.
