WebOct 30, 2024 · However, the construction of photothermal catalysts with strong light absorption and high catalytic activity remains a great challenge. In this work, integrated cobalt single-site catalysts (Co SSCs), coupled with strong photothermal conversion, high catalytic activity, and stability, are employed to catalyze the glycolysis of polyesters. WebPETG or glycolysis polyester is a variation of PET and the most commonly used PET in the additive manufacturing market. It is an amorphous and recyclable plastic with the characteristics combined of PLA and ABS. Advantage. PET is a strong, durable and recyclable material; It can be sterilized to use in the food packaging industry
