Abstract: YSZ has been wildly used in gas sensors because of its high ionic conductivity and excellent termostability. In this paper, the structure, the characteristics, and the research progress of NO2 sensors based on YSZ are briefly introduced. In particular, the three main factors (three-phase boundary, material type and morphology) which may affect the performance of the sensor are reviewed. The results indicated that the large three-phase boundary, new sensitive materials, and the different morphology of the sensitive materials can improve the the sensing properties. Finally, the development direction and application prospects of YSZ-based mixed-potential NO2 gas sensors are summarized. A favorable focus on developing materials with different morphology is proposed.
Key words: YSZ; TPB; sensitive material; mixed-potential
