Abstract
The invention is a nitrogen oxide trap comprising a porous support; and catalysts consisting of manganese and potassium loaded on the porous support. The trap may be used in an internal combustion engine exhaust gas catalyst system. During lean-burn operation of the engine the trap sorbs nitrogen oxides and releases the nitrogen oxides during decreased oxygen concentration in the exhaust gas.
