基于分子印迹技术，研制了一种用于甲醛检测的新型气体传感器。我们小组第一次用MIT来识别有机小分子。采用印迹聚合的方法，以甲醛为模板，Ag-LaFeO3为底物，合成了具有极高表面体积比的小尺寸分子印迹纳米颗粒（min）。其结构为正交钙钛矿结构。然后将敏管打印到氧化铝管上。随后，实现了用于甲醛检测的高选择性分子印迹气体传感器。在86℃时，基于传感器对0.5 ppm甲醛的响应为16，对其他测试气体的响应小于2。响应时间为55 s，恢复时间为40 s。
A novel gas sensor for the determination of formaldehyde was developed based on molecular imprinting technique (MIT). MIT was for the first time used to recognize small organic molecule by our group. The molecular imprinting nanoparticles (MINs) with a small dimension which possess extremely high surface-to-volume ratio were synthesized using imprinting polymerization with formaldehyde as template and Ag-LaFeO3 as substrate material. The structure of the MINs is orthogonal perovskite. And then the MINs were printed onto an alumina tube. Subsequently, a high selectivity molecular imprinting gas sensor for detection of formaldehyde was achieved. At 86°C, the response to 0.5 ppm formaldehyde based on the sensor is 16, and the response is lower than 2 for the other test gases. The response time and recovery time are 55 s and 40 s, respectively.
