Abstract: In this paper, the PET depolymerization catalyzed by metal oxides (MgO, CdO, Cu₂O, Sb₂O₃, MnO₂, V₂O₅, SiO₂, MoO₃) under microwave irradiation were investigated, and the effects of acid-base on PET depolymerization was studied by acid-base scale method. The results indicated that the stronger the acidity or basicity of metal oxide was, the better the effects of catalytic depolymerization of PET appeared. Compared with alkali metal oxide, the catalytic effect of acid metal oxide to PET depolymerization was better.
