Abstract
⺠In-situ investigation of carbonate lean NOx traps via impedance spectroscopy. ⺠Conductivity and activation energy of BaCO3 and Ba(NO3)2 in the range of 300-550 °C. ⺠Conductivity increases reversible sorbing NO2 on BaCO3 or K2CO3. ⺠Stepwise NOx accumulation detected electrically. ⺠K2CO3 dominates in mixture due to 5 orders of lower conductivity.
