| Abstract | The dependency on morphology is crucial for achieving highly efficient direct decomposition of NO. Herein, a BaCoO3 /CeO2 catalyst is synthesized using CeO2 small particles (p), spheres (s) and rods (r) as supports. The NO conversion to N-2 (NTN2) at 800 C-degrees follows the order BaCoO3 /CeO2-r (78.8 %) > BaCoO3 /CeO2 -s (75.9 %) > BaCoO3 /CeO2 -p (56.9 %) > BaCoO3 (8.6 %) at a space velocity 1 g s/cm(3) . BaCoO3 /CeO2 -r exhibts high tolerance to O-2 and stability with conversion decreasing from 78.8 % to 74.6 %, 60.0 % and 50.0 % at 800 degrees C with 1, 5 and 10 vol% O-2 , respectively. The high redox activity, higher active oxygen mobility and NO adsorption capability ensures its superior performance, while the high surface area (31.29 m( 2)/g) and uniform distribution of active sites on the surface further promote the activity. The mechanism of NO direct decomposition is elucidated by in situ Diffuse reflectance infrared Fourier transform spectroscopy, O-18(2) isotopic transient exchange experiments and density functional theory (DFT) calculation. |
