Catalytic performance of perovskite-type (ABO3) and K2NiF4-type (A2BO4) oxides for the reduction of NOx by diesel soot particulate in the presence of excess oxygen, that is, the simultaneous removal of NOx and soot, has been investigated. Their catalytic activity, evaluated from the ignition tempera

β¦ Synopsis
There has been a great deal of recent activity in the catalytic removal of NOx. This manuscript provides an analysis of the recent research methodology in this field, with a brief analysis of NO~ reduction with hydrocarbons (vs. other reductants), the decomposition on NO into N2 and 02, and processes that do not produce NOx. Limiting features of the current catalytic approaches to NOx removal are discussed. The current effectiveness of recent catalytic NO~ removal is assessed. Further, suggestions are offered to help future investigators focus on key experimental parameters and on opportunities for additional research that offer major societal and economic impact.

An active perovskite-type catalyst (La 0.8 K 0.2 Cu 0.05 Mn 0.95 O 3 ) was prepared and characterized using XRD, BET, and SEM. Then, the effect of catalysis on plasma assisted catalytic removal of nitrogen oxides and soot was investigated by combining temperature programmed reaction (TPR) and the an
