• W3190355873 abstract "Herein, supporting g-C 3 N 4 embedded with benzene-ring (BCN) on P-modified g-C 3 N 4 (PCN) successfully synthesized the homogeneous photocatalyst BCN/PCN (PBCN) via a simple thermal polymerization reaction. Under blue-light (LED) irradiation, the optimized PBCN (0.448 min −1 ) demonstrated excellent photocatalytic performance, attaining over 74 times the degradation rate for sulfisoxazole (SSZ) in contrast to non-functionalized g-C 3 N 4 (CN, 0.006 min −1 ). Theoretical calculations revealed that the substitution of heterocyclic rings in the g-C 3 N 4 triazine networks with benzene-rings enabled them to serve as electron donors, while promoting photoinduced spatial charge dissociation. Further, the carrier PCN tended to serve as electron acceptors to form electron-rich corner-phosphorous sites. Reactive species experiments demonstrate that the O 2 ˙ − and h + constituted the primary photocatalytic mechanism of SSZ degradation. The potential SSZ degradation routes were predicted based on the transformation products via mass spectrometry. Finally, the composite materials also exhibited excellent photocatalytic activity in the conversion of solar energy to chemical energy (H 2 O 2 ). This study guides the rational modification of g-C 3 N 4 -based semiconductors to achieve green energy production and beneficial ecological applications. • A novel double-functionalized PBCN composite is fabricated via a three-step process. • DFT elucidates the alteration of electronic structure promotes the charge transfer. • PBCN 0.05 delivers a high SSZ degradation rate over 74 times better than bulk CN. • The mechanism for SSZ degradation by the light/PBCN 0.05 system is proposed. • PBCN 0.05 exhibits great photocatalytic performance for H 2 O 2 production." @default.
