| description | The present invention relates to a catalytic article comprising a substrate having a catalyst composition disposed thereon, wherein the catalyst composition comprises a platinum group metal impregnated onto a porous support and a selective catalytic reduction catalyst, wherein the catalyst composition is substantially free of platinum; and wherein the catalytic article is effective in the abatement of nitrogen oxides (NOx) and hydrocarbons (HCs). The present invention further relates to exhaust gas treatment systems for treating an exhaust gas stream exiting a diesel engine. |
