NO/sub x/ reduction catalyst for internal combustion engine emission control

Patent ·
OSTI ID:6407831
A process is disclosed for reducing the oxides of nitrogen in exhaust gases from an internal combustion engine comprising contacting the exhaust gases with a self supporting catalytic structure in the form of an expanded thin metal foil. The expanded metal foil comprises a corrosion resistant metallic substrate having an NO/sub x/ reducing catalyst on the surface layer. The corrosion resistance substrate may be a nickel/chromium alloy, and the NO/sub x/ catalytic surface may be a nickel/copper alloy.
