Developing a Highly Efficient and Magnetically Recoverable Nanocatalyst for Glycolytic Depolymerization of Various Polyesters.

ABSTRACT: The synthesis of a new recyclable magnetic catalyst consisting of silica-coated magnetite nanoparticles (Fe₃O₄@SiO₂) with a zinc-containing ionic liquid anchored to the surface is described. An in-depth characterization was performed using different techniques, which demonstrated that Fe₃O₄@SiO₂@(mim)-[ZnCl-(OH)₂] (mim: methylimidazolium) depicts the actual structure of the nanocatalyst. This system exhibits an outstanding performance as a magnetically recoverable catalyst for the glycolysis of different polyesters in ethylene glycol, such as polyethylene terephthalate (PET), poly-(1,4-butylene terephthalate) (PBT), and bisphenol A polycarbonate (BPA-PC). The depolymerization of PET and PBT into bis-(2-hydroxyethy
