The present disclosure relates to a substrate containing passive NOadsorption (PNA) materials for treatment of gases, and washcoats for use in preparing such a substrate. Also provided are methods of preparation of the PNA materials, as well as methods of preparation of the substrate containing the PNA materials. More specifically, the present disclosure relates to a coated substrate containing PNA materials for PNA systems, useful in the treatment of exhaust gases. Also disclosed are exhaust treatment systems, and vehicles, such as diesel or gasoline vehicles, particularly light-duty diesel or gasoline vehicles, using catalytic converters and exhaust treatment systems using the coated substrates.

Compositions for passive NOx adsorption (PNA) systems and methods of making and using same

The present disclosure relates to micron-sized particle used for catalyzing and storing NOgases, such as those found in vehicle exhaust emissions, washcoats employing micron-sized particle used for catalyzing and storing NOgases, washcoat coated substrates, lean NOtrap (LNT) systems, and vehicles using such systems. Also provided are methods of preparing micron-sized particle used for catalyzing and storing NOgases, as well as preparation of washcoats and coated substrates. More specifically, the present disclosure relates to a lean NOtrapping materials, wherein the materials include a NOcatalytic component attached to a micron-sized carrier particle and a NOstorage component, as well as washcoats and coated substrates useful in the treatment of exhaust gases. In some embodiments, a portion of the NOstorage component is attached to the micron-sized carrier particle.
