The present invention provides a system and method for reducing nitrogen oxides in a diesel exhaust containing hydrogen and carbon monoxide on a palladium-based catalyst. Wherein the catalyst comprises a compound represented by the formula X% Pd-Y% V 2 O 5 / Z wherein X is about 0.1 to about 2.0, Y is about 0.1 to about 7.0, and Z is an oxide support to be.n n n n Diesel engine exhaust gas, nitrogen oxide, palladium catalyst, oxide carrier, catalytic converter, space velocity |
