Unravelling the mechanism of lanthanum-enhanced Pd-SSZ-13 zeolite against phosphorus-poisoning for passive NO adsorber

Key Points

• Lanthanum treatment significantly increases the resistance against phosphorus-poisoning in zeolite materials.
• Specifically, the lanthanum-enhanced Pd-SSZ-13 zeolite outperformed untreated variants in NO absorption capabilities.
• The study utilized observational analysis to examine the zeolite’s performance under phosphorus exposure.
• These findings may enable advancements in developing more effective NO adsorbers for environmental applications.
