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.

以金黄色葡萄球菌为模板的分层介孔 SnO2 纳米管通过静电纺丝实现三乙胺的高灵敏度检测

在这项工作中，首次以金黄色葡萄球菌（S. aureus）为模板，在静电纺丝实验中与PVP偶联，Sn ²⁺与金黄色葡萄球菌和PVP结合，通过静电纺丝形成纳米纤维。最后，我们得到了纳米纤维煅烧后的分级介孔SnO ₂纳米管。作为三乙胺 (TEA) 气体传感器的分级介孔 SnO ₂纳米管显示出高灵敏度、更好的循环稳定性和选择性。分级介孔 SnO ₂纳米管对 10 ppm TEA的响应和恢复时间约为 19 s 和 10 s。
