摘要
MnMoO 4 has excellent electrochemical properties and is widely used in the field of electrochemistry. In this study, MnMoO 4 with rod-like structure was successfully prepared by simple solvothermal method and used as sensitive material for gas sensors. The gas sensing performance shows that the response of MnMoO 4 -based sensor to 50 ppm triethylamine is 224.2, which is 2.3 times higher than that of pure MoO 3 . That reason why MnMoO 4 exhibits better sensitivity is that the increase of oxygen vacancy content gives the surface of MnMoO 4 material abundant active sites. In addition, its large baseline resistance is also conducive to the improvement of gas sensitivity. These factors make the MnMoO 4 -based sensor exhibit high response to triethylamine. What’s more, the sensor also has excellent selectivity, satisfactory repeatability, and long-term stability to triethylamine under chemical sensitization and synergistic action. This work provides a new thinking for the application of MnMoO 4 in gas sensors.
