ABSTRACT:
This invention is a bimetallic catalyst comprising tungsten oxide and platinum in critical amounts on a mostly .gamma.-alumina support material. It is particularly optimal for use in lean-burn engine exhaust systems, including gasoline and diesel, where it efficiently reduces NOx in the exhaust gas.
