    摘要: Provided is a diesel particulate filter capable of removing soot from an exhaust gas while operating at low backpressure, the filter comprising (a) a wall-flow filter substrate having a mean pore size, an inlet side, an outlet side, and a porous interior between the inlet and outlet sides; and (b) a catalyst composition coated from the inlet side of the substrate, wherein the catalyst composition has a d50 particle size distribution, wherein the d50 particle size distribution is less than the mean pore size divided by 4.9, and wherein the outlet side is substantially free of a catalyst coating.
