Ultrasound-assisted synthesis of graphene oxide (GO)–manganese oxide nanocomposite (GO/Mn₃O₄) was performed without further modifi cation of GO. Intensive ultrasound could reduce reaction steps and temperature, enhance the reaction rate and achieve Mn₃O₄ phase. The synthesized nanocomposite highly promoted glycolysis of poly(ethylene terephthalate) (PET) as a catalyst.
