The currently used three‐way catalyst in passenger cars reduces CO, H 2 , and NO x in the exhaust if O 2 is stoichiometrically introduced to the motor. However, the new lean‐burn engines work with an excess of O 2 , thus, requiring less fuel and producing less CO 2 . The currently used catalyst is not able to reduce NO x under oxidizing conditions. The results of NO x reduction by H 2 and CO under oxidizing conditions are presented and discussed.
