  • Catalytic washcoat with controlled porosity for NOabatement
    Patent number: 11717814
    Abstract: The present disclosure recognizes a correlation between zeolitic surface area (ZSA) of a catalyst composition and its catalytic activity. Particularly, the disclosure provides catalyst articles for diesel NOx abatement, including a substrate and a washcoat layer containing metal-promoted molecular sieves, wherein the zeolitic surface area (ZSA) of the catalyst article is about 100 m2/g or greater, the volumetric surface area is about 900 m2/in3 or greater, and/or the total zeolitic surface area (tZSA) is about 1200 m2 or greater. The disclosure further relates to methods for evaluating ZSA, volumetric ZSA, and tZSA, e.g.
