摘要
Photocatalysis offers promising technology for converting plastic waste into valuable chemicals. However, fully digging out the embedded value to incentivize the valorization of plastic waste is still a challenge. Herein, we first design an intramolecular donor–acceptor (D–A) structure by introducing the terephthalic acid (PTA) derived from polyethylene terephthalate (PET) waste into P-doped g-C3N4 (CN-P). Impressively, CN-P-PTA exhibits higher activity in the photocatalysis of PET to H2O2 compared with CN-P. The superior performance is attributed to the prolonged photogenerated carrier lifetime and the enhanced delocalization of π electrons. Moreover, single-particle PL quenching and DFT calculations reveal that PTA and CN-P can form an intimate interface via π–π conjugation, which facilitates the flow of photoexcited electrons from PTA to CN-P.
