| titleOfInvention | MO for aniline gas sensor2/MO3NMNPs hollow microsphere material and preparation method thereof |
| abstract | The invention belongs to the field of sensors, relates to detection of aniline gas, and particularly relates to MO (molybdenum oxide) for an aniline gas sensor 2 /MO 3 NMNPs hollow microsphere material and its preparation method. The application adopts a two-phase microemulsion method to prepare MO 2 And calcining the precursor in argon to remove organic matters in the precursor, stabilizing the hollow structure of the precursor, and then calcining the precursor in air again to perform oxidation treatment on the precursor. Calcining in two steps of different atmospheres to obtain MO with a heterostructure 2 /MO 3 The gas-sensitive performance is further improved by the hollow microspheres and the surface of the microspheres is modified with the noble metal nano particles. The detection capability of the hollow microsphere gas-sensitive material prepared by the invention on the aniline gas is obviously improved, and the minimum detection limit is 0.5 ppm; the response recovery time to the aniline gas is 23 s and 14 s respectively, and after 6 months of stability test, the device can keep more than 98% of the initial response value. |
