Adjusting the position of active components is critical to enhancing the activity of CHA structured small-pore zeolites for NO selective catalytic reduction. We herein synthesized a novel low-cost multi-metal Cu-Ce-La-SSZ-13 catalyst via a simple one-pot method and revealed the relationship between the position of active species and catalytic activity. The introduction of Ce4+ ions and La3+ ions can effectively regulate the Cu2+ cations to migrate from eight-membered rings to more active six-membered rings, which endows Cu-Ce-La-SSZ-13 with excellent low-temperature SCR activity.
