Research on Perovskite Catalysis for Diesel Engine Exhaust Removal

Diesel engine emissions of nitrogen oxides and particulates are the major source of air pollution that is a serious threat to human health. Diesel emissions treatment technology meet the increasingly stringent emission standards through the current difficulty and develop a new diesel engine exhausted treatment technology to further reduce the nitrogen oxide and particulate emissions are from diesel engines. In this paper, La1-xAxCo1-yByO3complex perovskite catalysts for diesel engine exhaust emission purification carry out the relevant research, this article firstly study the perovskite oxide catalyst preparation methods, as the catalyst preparation process are described .Then the activity of the catalyst samples obtain some useful results.
