Abstract
Processes for manufacturing nitrogen oxide storage materials and lean NOx trap catalysts are disclosed. Also disclosed are nitrogen oxide storage material made by processes comprising barium carbonate (BaCO) and ceria (CeO) by using Ba(OH)instead of most or all Ba(OOCH)to reduce cost and reduce harmful byproducts. Aspects of the present invention also relate generally to lean NOtrap (LNT) comprising nitrogen oxide storage materials.
