Abstract:
The invention relates to a coating composition for diesel oxidation catalysts or a combination of diesel oxidation catalysts and diesel particle filters, said coating composition comprising a combination of a noble metal on a metal oxide, with the exception of cerium oxide, and a zeolite doped with iron. The invention also relates to a catalyst provided with the coating according to the invention, and to a method for treating the exhaust gas of diesel internal combustion engines.
