DPF Supporting Nano-Structured Perovskite Catalysts for NOx and Diesel Soot Emission Control in Commercial Vehicles 2007-01-4173
Nano-structured perovskite-type oxides catalysts La1-xAxFe1-yByO3 (where A = Na, K, Rb and B = Cu), prepared by the Solution Combustion Synthesis (SCS) method and characterized by BET, XRD, FESEM, AAS and catalytic activity tests in microreactors and engine bench, proved to be effective in the simultaneous removal of soot and NO, the two prevalent pollutants in diesel exhaust gases in the temperature range 350-450°C. The best compromise between soot and nitrogen oxide abatement was shown by La-K-Cu-FeO3 catalyst which displayed the highest catalytic activity towards carbon combustion and the highest NO conversion activity.
