Abstract
A series of La2Sn2-xFexO7 (x=0, 0.2, 0.6, 1.0, 1.4, 1.8, 2.0) catalysts were prepared by a constant pH co-precipitation method, and their catalytic activity was investigated for simultaneous removal of NOx and soot. The incorporation of Fe strongly influences the crystal phase composition, surface area and redox properties of the catalysts. All the catalysts displayed soot oxidation activity with nearly 100% selectivity towards CO2. The doped solids exhibit higher activities than the undoped one, which may be related to the enhancement of reducibility derived from structure defects induced by doping. LSF0.6 may be a good catalyst with high soot oxidation activity (Ti = 334 °C) and a high maximum productivity of N2 (PN2= 12.4%).
