Pt-promoted Ce-Zr oxide was identified as a promising candidate for passive NOx adsorber applications. NOx storage efficiency significantly improved with increasing storage temperature in the range 80-160 °C, while both storage temperature and storage time were found to play important roles in NOx desorption behavior.
