摘要:
SnO2-In2O3hierarchical microspheres were prepared by the hydrothermal and solvothermal method. The morphology, phase crystallinity of the obtained SnO2-In2O3were measured by X-ray diffraction(XRD), scan electron microscopy(SEM), respectively. A room temperature ozone sensor based on SnO2-In2O3hierarchical microspheres was fabricated and investigated. The gas sensing properties of the sensor using SnO2-In2O3strongly depended on the proportion of SnO2and In2O3. The sensitivity and response/recovery speed were greatly enhanced by UV illumination. A gas sensing mechanism related to oxygen defect was suggested.
