Smart recycling of PET to sorbents for insecticides through in situ MOF growth

Research and progress of chemical depolymerization of waste PET and high-value application of its depolymerization products

“…Semyonov et al 16 partially hydrolyzed the PET bottle flakes by HNO 3 solution and DMF ( N , N -dimethylformamide), and the carboxyl groups generated on the surface of the PET bottle were used as a linker for subsequent surface connection and nucleation. By adding ZrCl 4 , free TPA and zirconium ions are compounded, and finally the organic metal frame material is grown on the surface of the PET bottle flake to prepare the mixed material frame (UiO-66).…”

Upcycling hazardous metals and PET waste-derived metal–organic frameworks: a review on recent progresses and prospects

“…Surface-assisted MOF development helps increase it by 100 times than that in UiO-66. 24 Two-step methods involve the depolymerization of plastics, followed by MOF synthesis. In the first step, PET bottles are converted to small pieces and washed for the hydrolysis process.…”

MFI, BEA and FAU zeolite scavenging role in neonicotinoids and radical species elimination

“…17 In order to solve several emerging problems, Semyonov et al proposed recycling polyethylene terephthalate as a support for metal–organic framework growth and subsequent imidacloprid removal in a fixed-bed system. 18 Composite systems, such as Ag nanoparticles supported on chitosan stabilized biochar 19 and hydrogels with microporous polymers and graphene oxide, were also applied for NNI removal. 20 NNI adsorptive properties are convenient for solid-phase extraction using a magnetic nanohybrid zeolitic imidazolate framework, for water analysis.…”
