Effect of NO2 Concentration on Sensitivity for High Temperature Impedancemetric NOx Sensors

摘要：

　　With the growing problem of automobile exhaust pollution,the study of automotive oxygen sensor is very meaningful,nitrogen oxides accounts for a large proportion of automobile exhaust.AC impedance spectroscopy of the NOx sensor in different temperature (773K,873K,973K) and NO2 of different concentrations (100ppm,500ppm,1000ppm) in this paper,the influence of temperature and gas concentration on NOx sensors is explored.
