Title
Direct NO decomposition over C-type cubic Y2O3–Pr6O11–Eu2O3 solid solutions
Abstract

•C-type cubic Y2O3–Pr6O11–Eu2O3 solid solutions were synthesized.•Substitution of Y with Eu enhances the NO decomposition activity of Y2O3–Pr6O11 solid solutions.•The catalysts show high tolerance to O2 and CO2 coexistence.

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)2O3±δ catalyst exhibited high NO decomposition activity; NO conversion to N2 was as high as 84% at 900 °C in the absence of O2 (NO/He atmosphere). This catalyst also sustained a high level of NO conversion even in the presence of O2 or CO2, compared with those of the conventional perovskite-type catalyst for direct NO decomposition.
