Improving NOx storage and CO oxidation abilities of Pd/SSZ-13 by increasing its hydrophobicity

•2wt% of Pd was successfully atomically dispersed in hydrophilic/hydrophobic SSZ-13.•Pd/SSZ-13 became hydrophobic after high temperature treatment (750 °C) under H2O.•The concentration of dehydrated Pd ions increased in hydrophobic Pd/SSZ-13.•Hydrophobic Pd/SSZ-13 displayed excellent performance as Passive NOx Adsorber.•Hydrophobic Pd/SSZ-13 displayed excellent performance as CO oxidation catalyst.
