ABSTRACT:
A catalyst for purification of diesel engine exhaust gas is disclosed which comprises having (A) a catalytic component comprising the two elements of iron and manganese and a refractory inorganic oxide and optionally an alkaline earth element and/or a rare earth element and (B) a catalytic component comprising at least one noble metal selected from the group consisting of palladium, platinum, and rhodium and a refractory inorganic oxide and optionally copper deposited in the form of a single layer on a refractory three-dimensional structure. This catalyst is capable of removing such harmful components as carbonaceous particulates, unburned hydrocarbons, and carbon monoxide from the diesel engine exhaust gas and, moreover, suppress the formation of sulfates from sulfur dioxide.
