Polyethylene terephthalate (PET) as one of non-degradable wastes has become a huge threat to the environment and human health. Chemical Recycle of PET is a sustainable way to release 1,4-benzenedicarboxylic acid (BDC) the monomer of PET as common used organic linker for synthesis of functional Metal–organic-frameworks (PET-derived MOFs) such as UiO-66, MIL-101, etc. This sustainable and cost-effective “Waste-to-MOFs” model is of great significant to be intensively investigated in the past years. Attributes of substantial porosity, specific surface area, exposed metal centers, uniform structure, and flexible morphology render PET-derived MOFs are well-suited for applications in adsorption, energy storage, catalysis, among others. Herein, in the present work, we have summarized recent advances in synthesis of PET-derived MOFs using ex-situ and in-situ methods for typical applications of adsorption, catalysis and energy storage. Despite those improvements in synthesis methods and potential applications, challenges still remain in development of green and economical routes to fully utilize waste PET for massive manufacture of valuable MOF materials and chemicals. This review provides insights into the conversion of non-degradable PET waste to value-added MOF materials, and further suggests promising perspectives to develop the sustainable “Waste-to-MOFs” model in addressing environmental pollution and energy crises.
“Waste-to-MOFs” model that chemical recycle of waste plastic to synthesize MOFs as functional materials offers one of sustainable strategies to relieve the plastic pollution. Here, recent achievements on in-situ and ex-situ utilization of waste polyethylene terephthalate for synthesis of value-added 1,4-benzenedicarboxylic acid-based MOFs are reviewed according to typical applications of adsorption, catalysis and energy storage.
