The aim is to improve the efficiency of ZnO in catalyzing the depolymerization of waste polyester.
Enhanced photothermal catalytic performance via oxygen vacancies in ZnO.
Used 2.2 W•cm -2 irradiation to heat the reaction.
Monitored temperature rise to achieve catalysis.
Catalyst raised the reaction temperature to 190°C rapidly under specific irradiation.
High-purity BHET was obtained from waste polyester.
Significant improvement in catalytic performance through defect integration.
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...
