Effect of Ions Substitution on Nanospace La-Fe-O Catalytic Properties for Simultaneous Removal of NO_x and Soot

Abstract:

The catalysts La_0.8K_0.2FeO₃(LKFO), La_0.8K_0.2Fe_0.7Mn_0.3O₃(LKFMO) and La_0.8K_0.2Fe_0.67Mn_0.3Pt_0.03O₃(LKFMPO) were prepared by the citrate-gel process and the catalyst-coated honeycomb ceramic devices were prepared by the citrate-gel assisted dip-coating method. All the catalysts have a high performance on the simultaneous removal of NO_x and soot at a temperature range of 200 to 400°C under the practical diesel exhaust emission. The obvious catalytic improvement is largely due to the effects of ions substitution, pore structure and microstructural characteristics of the catalysts. The catalytic performance order is LKFMPO > LKFMO > LKFO. Among them the LKFMPO catalyst shows the best catalytic properties, especially in the removal of NO_x, with a maximum conversion rate of NO_x (21.2%).
