摘要：
A multifunctional catalyst, a method of preparing the catalyst and the use of the catalyst in treating exhaust fumes from internal combustion engines are described. The catalyst includes a porous layer containing (weight %, dry):about 50 to about 99.7% of at least one refractory inorganic oxide,about 0.1 to about 25% of at least one uranium oxide,about 0.1 to about 35% of at least one oxide of at least one metal P selected from the group consisting of lithium, sodium, potassium, rubidium, cesium, beryllium, magnesium, calcium, strontium, barium, lanthanum, praseodymium, neodymium, gadolinium, and yttrium andabout 0.1 to 20% of a metal A selected from the group consisting of platinum, rhodium, palladium, ruthenium, iridium, and mixtures thereof.
