Abstract:
We report a strategy to enhance the photothermal catalytic performance of ZnO by introducing oxygen vacancies. Under 2.2 W cm-2 irradiation, the catalyst rapidly elevates the reaction temperature to 190 °C, achieving complete PET conversion within 1 h and yielding BHET with a purity of approximately 96%, substantially outperforming pristine ZnO.

Types of Step-Growth Polymers: Polyesters
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...
