Abstract in another language
Modern exhaust gas aftertreatment systems need robust and reliable sensors for in-situ control. We present a novel gas sensor that is easy to manufacture and should provide sufficient long-term stability. The impedimetric device is based on gas-depended electrical changes of a NOx storage material, operated at higher temperatures in an equilibrium state. Experimental results demonstrate a stable baseline of the signal, high NOx sensitivity and good NOx selectivity regarding the missing influence of several typical exhaust gas components like CO, H2, CO2, or H2O. Notably, we found also low ammonia cross sensitivity. Therefore, the sensor device is an interesting candidate for exhaust applications, especially in the field of selective catalytic reduction (SCR) systems.
