C-type cubic Y2O3-Pr6O11-Eu2O3 solid solutions were synthesized by a co-precipitation method and their catalytic activities for direct NO decomposition were investigated. Among the catalysts synthesized, the (Y0.78Pr0.15Eu0.07)(2)O3+delta catalyst exhibited high NO decomposition activity; NO conversion to N-2 was as high as 84% at 900 degrees C in the absence of O-2 (NO/He atmosphere). This catalyst also sustained a high level of NO conversion even in the presence of O-2 or CO2, compared with those of the conventional perovskite-type catalyst for direct NO decomposition.
