Abstract

A series of La₂Cu_(1-x)Fe_xO₄ 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, La₂Cu_0.7Fe_0.3O₄ 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.
