The carbonates precursor with Mn and Ni were synthesized by precipitation method under low temperature. The MnO2/NiO nanocomposite microspheres were prepared after calcinated treatment. The morphology and structure of materials were studied by SEM and XRD. The results show that the diameter of MnO2/NiO nanocomposite microspheres is about 2 μm. The nanoparticles on the surface of microsphere arrangement sloppy,and there are mesoporous in the port of nanoparticles. The MnO2/NiO-2 thin film sensor has good gas sensing response to NOxat room temperature. When the concentration of NOxreaches 100 ppm,sensitivity is 36% and the response time is 11 s. The limit level of MnO2/NiO-2sensor to NOxis 3 ppm.
