Abstract
Under the context of circular material economy
this study developed a series of oxygen vacancy-tunable TiO
2
-based catalysts to enable green synthesis and in-situ closed-loop recycling of bio-based poly(ethylene 2
5-furandicarboxylate) (PEF). By precisely regulating oxygen vacancy density on TiO
2
catalyst surfaces
catalytic activity for the polymerization reaction between 2
5-furandicarboxylic acid (FDCA) and ethylene glycol was significantly enhanced
successfully producing high intrinsic viscosity PEF ([
η
]
=0.728 dL/g). The catalytic system innovatively drove PEF depolymerization under mild conditions without additional catalysts
achieving complete depolymerization. Depolymerized products could be directly repolymerized
yielding recycled PEF (rPEF
[
η
]
=0.864 dL/g) with performance comparable to virgin material. The full-cycle polymerization-depolymerization-repolymerization process overcame energy and cost barriers in traditional polyester recycling
with its core mechanism lying in dynamic regulation of catalytic active sites by oxygen vacancy defects. This work provides an atomically economical and industrially viable strategy for addressing sustainable production and circular utilization challenges of bio-based polyesters.
