Abstract

A passive NOadsorber is disclosed. The passive NOadsorber is effective to adsorb NOat or below a low temperature and release the adsorbed NOat temperatures above the low temperature. The passive NOadsorber comprises a noble metal and a small pore molecular sieve. The small pore molecular sieve has a maximum ring size of eight tetrahedral atoms. The invention also includes an exhaust system comprising the passive NOadsorber, and a method for treating exhaust gas from an internal combustion engine utilizing the passive NOadsorber.
