中文摘要：

以sol-gel法制备的NASICON（Na3Zr2Si2PO12）为基体材料，掺杂了V2O5的TiO2为辅助电极材料，制备了一种管式结构的固体电解质SO2传感器。当工作温度为300℃时，以V2O5与（V2O5＋TiO2）的质量比为5％的材料为辅助电极材料时，传感器对体积分数为（1～50）×10^-6的SO2表现出了较好的气敏性能，传感器的电动势E值与SO2浓度的对数呈很好的线性关系，传感器的灵敏度为78mV／decade。同时，传感器对50×10^-6的SO2的响应恢复时间分别为10s和35s，且有较好的选择性。

英文摘要：

The solid-electrolyte SO2 gas sensor with pipe structure was fabricated, using NASICON（Na3Zr2Si2PO12） prepared by sol-gel method as based materials and V2O5-doped TiO2 as auxiliary electrode materials. When working temperature is 300 ℃ and （ [V2O5 ： （V2O5＋TiO2）] = 5 %, the sensor has good gas sensing properties to （1-50）×10^-6 SO2. The E value of the sensor is almost proportional to the logarithm of SO2 concentration, and the sensitivity （slope） is 78 mV/decade, The response time to 50×10^-6 SO2 is 10 s, and the recovery time is 35 s. The sensor shows a good selectivity to SO2.
