Abstract:
The present invention relates to catalyzed soot filter comprising a porous wall flow substrate, a catalyst for selective catalytic reduction (SCR), a palladium component, and a platinum component, the wall flow substrate comprising an inlet end, an outlet end, a substrate axial length extending between the inlet end and the outlet end, and a plurality of channels defined by internal walls of the wall flow substrate, wherein the plurality of channels comprise inlet channels having an open inlet end and a closed outlet end, and outlet channels having a closed inlet end and an open outlet end, and the SCR catalyst is provided on the entire surface of the inlet channel walls and on at least a portion of the surface of the pores within the channel walls underneath the surface of the channel walls coated with the SCR catalyst.
