Abstract Pd‐based zeolites are extensively used as passive NO x adsorbers (PNA) for cold‐start emissions to meet stringent emission regulations. However, optimizing adsorber design reduce Pd usage with substitution by non‐noble metals that prone suffer from H 2 O remains a significant challenge. Herein, the core–shell Mn/CHA@Pd/CHA zeolite monoliths based on metal/zeolite core constructed using coaxial 3D printing technology and identified efficient first time. In monolith, Pd/CHA shell effectively protected Mn active sites in O, while integration of Mn/CHA not only introduced storage but also facilitated desorption, thereby achieving comparable adsorption properties increased desorption efficiency 35% at 350 °C compared monolith. Furthermore, some metal‐based (e.g., Co/CHA, Mn/MFI, Mn/BEA) Pd/AEI) employed cores shells respectively fabricate series via printing, highlighting benefits incorporating into improving behaviors. This work provides promising strategy designing cost‐effective PNA materials contributes exhaust after‐treatment technology.
