Abstract
Polyethylene terephthalate (PET) waste, especially originating from post-consumer bottles, represents a significant environmental hazard owing to its widespread utilization and inadequate biodegradability. Addressing the growing environmental issues associated with plastic waste, the development of sustainable strategies for recycling and utilization is of paramount importance. This study explores the potential of employing waste plastic bottles, specifically PET, as a precursor in the synthesis of Metal-Organic Frameworks (MOFs). The synthesis procedure encompasses the depolymerization of PET to yield terephthalic acid, serving as an organic linker in the formation of MOFs. An analysis of the potential applications of PET-derived MOFs, including catalysis, adsorption, and gas separation, is conducted. The review also highlights prospects and challenges within the field, underscoring the necessity for further refinement, scalability, and commercialization of PET-sourced MOFs. The overarching aim is to foster the advancement of ecologically responsible methods for waste plastic management and the creation of valuable materials through MOF synthesis. • Utilization of waste plastic bottles as an alternative precursors for MOFs syntheses instead of commercially available terephthalate. • Comparison of various synthetic approaches including hydrothermal, solvothermal, and microwave-assisted are discussed for PET-derived MOFs. • Potential challenges for plastic degradation and the applications of PET-derived MOFs are discussed in the review.
