摘要：
The invention concerns a multifunctional catalyst containing cerium, uranium and at least one metal, for converting pollutants emitted by internal combustion engines, and their preparation.A catalyst comprises a porous layer containingfrom about 20% to about 99% of at least one refractory oxidefrom about 0.8% to about 70% of at least one cerium oxidefrom about 0.1% to about 50% of at least one uranium oxidefrom about 0.1% to about 20% of a metal selected from the group made up of Pt, Rh, Pd, Ru, Ir and Au, and mixtures thereof.Applications are in the catalytic converter industry.
