| 摘要 |
The invention provides a particulate combustion catalyst which includes an alumina porous carrier whose pore size distribution profile, as determined by means of a mercury porosimeter, has a peak falling within a range of 10 to 100 nm, and, as a catalytic component, an alloy containing Ag in an amount of 75 to 25 mass% and Pd in an amount of 25 to 75 mass%, the alloy being supported on the surface of the alumina porous carrier and/or on the inner walls of pores of the alumina porous carrier. The invention also provides a method for producing the particulate combustion catalyst, a particulate filter having the particulate combustion catalyst supported on a support, and a method for producing the particulate filter. |
