摘要：
A washcoat slurry comprising a platinum group metal (PGM) selected from the group consisting of Pt, Pd, Rh and mixtures thereof; an oxygen storage capacity (OSC) material having a D90 in a range of from 1 to 50 μm; an inorganic oxide support; an organic pore former; and a solvent is disclosed. A method for the manufacture of a catalytic gasoline particulate filter for the treatment of an exhaust gas comprises coating a wall-flow filter substrate with the washcoat slurry.
