Leveraging Mesoporosity and Acidity in Interzeolite Transformation Intermediates for Plastic Waste Valorization - replication data

Interzeolite Transformation Intermediates (ITIs) produced by the partial interconversion of FAU and BEA zeolites were systematically investigated as catalysts for the cracking of low-density polyethylene (LDPE) and polystyrene (PS). Catalytic performance was benchmarked against fully formed zeolites (FAU, BEA) and a mesoporous aluminosilicate (Al-MCM-41). For LDPE cracking, strong acidity and well-defined microporosity were found to be critical, with conventional zeolites outperforming ITIs. In contrast, ITIs exhibited superior catalytic activity and stability for PS cracking owing to their well-connected mesoporosity and balanced acidity profiles.
