ZPGM DIESEL OXIDATION CATALYSTS AND METHODS OF MAKING AND USING SAME

摘要

Diesel oxidation ZPGM catalyst systems are disclosed. ZPGM catalyst systems may oxidize toxic gases, such as carbon monoxide, hydrocarbons and nitrogen oxides that may be included in exhaust gases. ZPGM catalyst systems may include: a substrate, a washcoat, and an impregnation layer. The washcoat may include at least one carrier material oxides. The impregnation layer may include at least one ZPGM catalyst, carrier material oxides and OSMs. Suitable known in the art chemical techniques, deposition methods and treatment systems may be employed in order to form the disclosed ZPGM catalyst systems.
