Interfacial charge transfer in a gallium oxide/covalent organic framework heterojunction for enhanced photocatalytic degradation of perfluorooctanoic acid.
Per- and polyfluoroalkyl substances (PFAS), particularly perfluorooctanoic acid (PFOA), are highly persistent pollutants owing to their strong CF bonds and exceptional chemical stability. Herein, a sp2-conjugated covalent organic framework (COF)/gallium oxide (Ga2O3) heterojunction was constructed through an in situ gr...
