Abstract :
A series of La2Cu(1-x)FexO4 catalysts were prepared by the citric acid complex method and characterized by XRD. The catalyst activity of the catalysts was evaluated by a technique of the temperature-programmed reaction. Results showed that, La2Cu0.7Fe0.3O4 have high activity in simultaneous catalytic removal of PM and NOx. The research also investigated the impact of different O2 concentration on catalyst activity. Coated the catalyst in SiC support for the bench test, results indicated that the catalytic converter could achieve better emission control after reached the carbon light-off temperature.
