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

Abstract

An intense increase in non-biodegradable plastics and waste metals is an immediate threat to the world and needs to be addressed urgently. There are several strategies deployed to control, eliminate,...

“Functional upcycling” of polymer waste towards the design of new materials

“…First reason is that MOFs are functional compounds that serve materials in the adsorption/separation and decomposition of toxins. 111–113 Secondly, MOFs are of vital importance in science and technology because of their high surface area and controlled porosity. 114–116 BASF company successfully markets MIL-53(Al) type terephthalate MOFs, which is a considerable example showing the increasing demand for MOFs.…”

“…118–124 In addition, a range of UiO-66 powders was prepared by in situ hydrolysis and ZrO 2 addition, 123 and a detailed review of synthesising MOFs from PET has been recently published. 111,124…”

Waste PET upcycling to conductive carbon-based composite through laser-assisted carbonization of UiO-66

“…9,10 Here, PET was used as the support and feedstock for MOFs synthesis. 11 This allows for the design of a wide range of materials to remove the organic pollutants from the environment. 6,10 However, MOF applications are not limited to adsorption and catalysis.…”

Weak Bonds, Strong Effects: Enhancing the Separation Performance of UiO-66 toward Chlorobenzenes via Halogen Bonding

“…Indeed, the possibility of employing waste PET as a source of ligands for MOF construction has attracted significant research interest in terms of the development of functional upcycling methods. 15,26 For UiO-66-I opt growth on PET, a mixture of I-TA/TA ligands was synthesized by the Tronov−Novikov method 27 using PET waste as a feedstock (Figures S15 and S16). The prepared PET@UiO-66-I opt material was fully characterized using FTIR, XRD, XPS, BET, and scanning electron microscopy combined with energy dispersive spectroscopy (SEM-EDX), as described in the Supporting Information (Figures S17−S22 and Table S8).…”

“…Importantly, the use of PET waste as feedstock decreases the cost of the materials associated with this system. Indeed, the possibility of employing waste PET as a source of ligands for MOF construction has attracted significant research interest in terms of the development of functional upcycling methods. , …”
