Abstract
Provided are selective catalytic reduction catalytic articles, emission treatment systems and methods for simultaneously remediating the nitrogen oxides (NO), particulate matter, and gaseous hydrocarbons present in diesel engine exhaust streams. The catalytic articles have a Selective Catalytic Reduction (SCR) catalyst uniformly coated over the outlet portion of wall flow filter walls resulting in reduction of NOand combustion of the soot without substantially increasing the system backpressure.
