Polyethylene terephthalate (PET) is widely used in packaging and insulation due to its excellent mechanical strength and thermal stability. However, its high chemical stability also means that discarded PET is difficult to degrade and tends to accumulate in the environment, contributing to plastic pollution.

Our PET degradation catalyst is specifically designed to address this issue. Through chemical recycling, it efficiently converts PET into the monomer BHET, enabling closed-loop recycling of polyester materials and supporting a greener, more sustainable future.

Product Features
Green Catalytic System
The catalyst is based on an ionic liquid system, offering environmental benefits throughout both material selection and catalytic processes. It is reusable for over 50 cycles, delivering excellent cost-effectiveness.
High Catalytic Efficiency
At 190 °C, the catalyst achieves 100% PET degradation within 3 hours. The process yields over 95% product with a purity of more than 99%.
Ionic Liquid Catalytic Mechanism
Ionic liquids serve as the active catalytic components. The cations in the ionic liquid interact with the carbonyl oxygen (C=O) in ester bonds, facilitating a nucleophilic attack by the hydroxyl group in ethylene glycol, thereby breaking down PET chains efficiently.
Magnetic Nanoparticle Support
The ionic liquids are immobilized on magnetic metal nanoparticles, enhancing catalytic performance through synergistic effects. This design also allows easy catalyst recovery via magnetic separation.
