Hot Pickering emulsion interfacial catalysis accelerates polyethylene terephthalate (PET) glycolysis

Abstract

A stable hot Pickering emulsion interfacial catalysis (HPEIC) system was constructed by a kind of asymmetric silica nanonets (M-ANNs). The system achieved 100% depolymerization of PET with a yield of PET monomer more than 90% within 5 min at 170 °C.
