| description | The present invention relates to a catalytic wall-flow monolith for use in an emission treatment system,the monolith comprising a porous substrate and having a first face and a second face defining a longitudinal direction therebetween and first and second pluralities of channels extending in the longitudinal direction,wherein the first plurality of channels provides a first plurality of inner surfaces and is open at the first face and closed at the second face, and wherein the second plurality of channels is open at the second face and closed at the first face,wherein a first catalytic material is distributed within the porous substrate,wherein a microporous membrane is provided in the first plurality of channels on a first portion, extending in the longitudinal direction, of the first plurality of inner surfaces. |
