抄録

Solid electrolyte electrochemical devices based on sodium super-ionicconductor (NASICON: Na1+xZr2SixP3-xO12) and pyrochlore-type oxide(Pb2M2O7-y : M= Ir, Ru1-xPbx; x=0 - 0.75) electrodes were found to exhibitgood performance for the potentiometric sensing of NO as well as NO2 at 400°C.The EMF responses were almost linear to the logarithm of NO or NO2concentration. Among the elements tested, the device attached withPb2Ru1.5Pb0.5O7-y electrode gave excellent NO sensing properties, and the EMFchanged with changing gas concentration of NO diluted in N2 or NO diluted in anO2 and N2 mixture with negative or positive slope, respectively, while it keptalmost constant to the concentration change of NO2 and CO2 diluted in air.
