Description
Summary:Increasing quality of life requires low power consumption and reliable gas sensing technology for real-time monitoring of the environment. Herein, based on the principle of ion compensation and charge compensation, Mn-doped MoO 3 self-assembled nanoflowers were designed and prepared, and their gas-sensing performance were studied. Benefiting from abundant defective sites and surface chemical state changes, the sensor exhibits superior characteristics for triethylamine detection, including ultrahigh response (436.9), short response time (7 s), small detection limit (1 ppm), and remarkable selectivity. The gas-sensitive mechanism of M-MoO 3 was explained from the points of view of charge compensation and ion compensation, and it was proved that the incorporation of Mn into MoO 3 was an effective way to improve its gas sensitivity. This work provides a potential strategy for widespread triethylamine detection and provides new ideas for the design of high-performance sensors.
