In this paper, a series of Pd/CeO2catalysts prepared by different synthesis routes and showing different morphological and textural properties have been investigated for passive NOxadsorption (PNA) applications. The results obtained by NOxadsorption/desorption tests demonstrated that NOxstorage capacity and NOxstorage efficiency of Pd/CeO2materials depend strictly on their surface area, whereas the morphology of the support and the Pd deposition method do not seem to play a key role. In contrast, the Pd deposition method does impact the dynamics of NOxdesorption by affecting the amount of NOxdesorbed at different temperatures. This seems to be connected to Pd–Ce interactions at the nanoscale that favor NOxdesorption at higher temperatures suitable for PNA application. These findings are relevant in designing and optimizing the properties of Pd/CeO2materials for their function as passive NOxadsorbers.
