摘要:The invention refers to a catalyst material for assisting carbon-containingparticulate matter combustion. The catalyst material being essentially free of platinumgroup metal compounds comprising a Copper-oxide and a silver metal component. This
catalytic composition is allowing decreasing NO2 emissions and higher maximal sootloadings during regeneration of catalyzed DPF while showing comparable or even betteractivity in soot oxidation regarding reference state-of-the-art CDPFs based on Pt-groupmetals. The new catalysts revealed high stability against deactivation during the mostsevere regenerations.
