چکیده انگلیسی
Perovskite-type electrode materials of the compositions La0.6Ca0.4B′1−xB″xO3±δ (B = Mn, Cr; B″ = Ni, Co, Fe; x = 0, …, 0.6) were investigated with regard to their NO sensitivity and the cross-sensitivity to NO2 and propylene in a potentiometric solid electrolyte measuring setup. The highest NO sensitivity was found for nickel and iron manganites with x = 0.2 and 0.3. Dependencies on the NO gas concentration were found using impedance spectroscopy. For some materials, the catalytic conversion of NO, NO2, methane and propene was determined by thermal investigation in the temperature range of 25-800 °C.
