Study of YSZ electrolyte inks for preparation of screen-printed mixed-potential sensors for selective detection of NOx and NH3
Résumé
Among all NOx reduction approaches, selective catalyst reduction (SCR) system is one the most reliable ways to control NOx emissions from diesel engine vehicles and trucks. In order to optimize the conversion rates of NOx and to prevent inducing excessive NH3 to the air, an NH3 and NOx sensor is required [1]. In this study, three different types of YSZ ink have been examined to identify the most effective electrolyte for NOx and NH3sensing. The results have shown that a home-made ink with YSZ powder shows the best sensitivity towards ammonia without polarization and the highest NO2/NO signal ratio with polarization current of 25 nA.
