| 摘 要： | 以钇稳氧化锆(简称YSZ,Yttria-Stabilized Zirco nia)为固体电解质,添加不同摩尔比例YSZ的NiO+YSZ混合体为敏感电极材料,通过丝网印刷技术制备了相应的混合电势型NOx传感器.采用XRD和SEM手段对NiO混合物进行了物理性能分析,利用电势和阻抗测量设备对传感器样品的输出电势(EMF)和交流阻抗等电学参数随NO浓度的变化进行了研究.结果显示:NiO+YSZ的混合体中,物相独立,没有新相产生；在相同NO检测环境下,敏感电极中YSZ所占摩尔比例为20mol%时传感器的响应电势最大且在0.O1 Hz～100 kHz范围内的阻抗谱最小,SEM也显示此时具有很好的TPB.

| Abstract: | Several mixed-potential-type NOx sensors were prepared by means of screen-printing technique using yttria-stabilized zirconia(8YSZ,8mol% Y2O3 doped)as electrolyte and some powders obtained by the NiO mixed with different proportion of YSZ as electrode material.The physical characteristics of sensors was analyzed by X-ray diffraction(XRD)and scanning electron microscope(SEM).Dependences of electromotive force(EMF)and complex impedance on the NOx concentration were studied by corresponding testing equipments,... |
