Abstract: Provided is a PET chemical recycling method. The PET chemical recycling method includes the following: adding a PET chemical recycling ion catalyst material for PET chemical recycling to PET waste and ethylene glycol; heating and stirring to obtain depolymerized and decolorized bis(2-hydroxyethyl)terephthalate (BHET); and filtering and recycling the ion catalyst material for PET chemical recycling. The PET chemical recycling ion catalyst material is a bisalkylimidazole-metal tetrachloride ionic liquid grafted on a porous carrier.
