ABSTRACTImpedance spectroscopy was applied on zeolite H-ZSM 5 as a proton conducting NH3 sensor material and DeNOx-SCR (selective catalytic reduction of NOx with NH3) catalysts at the same time under SCR conditions. We show that in situ monitoring of the NH3 conversion with NOx becomes feasible when the zeolite is loaded with NH3 first and NOx is applied afterwards to the gas phase. Temperature dependent measurements allow discriminating NH3 desorption from catalytic conversion and time dependent measurement give first hints on the thermal activation of the conversion.
