Abstract

NO direct decomposition is the most promising but also the most challenging approach for nitrogen oxides mitigation. Developing high performance catalysts is greatly desirable to promote the application of this technology. The present catalysts BaCoO3−CeO2 prepared by the one-pot method show superior activity towards NO direct decomposition, robust oxygen resistance and decent durability. The NO conversion to N2 of 5 %BaCoO3−CeO2 catalyst is 57.2 %, 70.1 % and 75.6 % at 700, 750 and 800 °C, respectively. It still maintains at 54.3 % even in the presence of 10 vol % O2 at 800 °C and is stable in 1 vol % O2 at least for 24 h at 750 °C. Such impressive performance is ascribed to the unique properties of CeO2, strong interaction between perovskite and CeO2, and microstructure of the catalysts rendered by the citric acid-nitrate one-pot method.
