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