Process for treating exhaust gas from internal combustion auto-ignition engines

Catalyst for treatment of internal combustion engine exhaust gases comprises a support with a porous layer based on a refractory inorganic oxide and an active phase comprising at least Ce, Fe and Pt. The layer comprises 0.3-4.4% Ce, 0.1-3.5 (0.1-2) % Fe, 0.003-0.04 (0.0035-0.03) % Pt and balance to...
