Complementary acid site mechanisms in hydrogen-free polyethylene upcycling: elucidating the distinct roles of Brønsted and Lewis sites in Ce-modified zeolites
DOI: 10.1039/D5GC01799H, PaperTaeeun Kwon, Jonghyun Park, Ki Hyuk Kang, Dae Sung Jung, Wangyun Won, Insoo Ro
Hydrogen-free upcycling of polyolefins over zeolite catalysts yields up to 88.7% naphtha. A linear structure–function relationship reveals that Brønsted acid sites promote β-scission, while strong Lewis acid sites enhance hydride abstraction.
