Enhanced Photocatalytic Properties of All-Organic IDT-COOH/O–CN S-Scheme Heterojunctions Through π–π Interaction and Internal Electric Field
Bibliographic record
Abstract
Herein, we present a distinct methodology for the in situ electrostatic assembly method for synthesizing a conjugated (IDT-COOH)/oxygen-doped g-C 3 N 4 (O–CN) S-scheme heterojunction. The electron delocalization effect due to π–π interactions between O–CN and self-assembled IDT-COOH favors interfacial charge separation. The self-assembled IDT-COOH/O–CN exhibits a broadened visible absorption to generate more charge carriers. The internal electric field between the IDT-COOH and the O–CN interface provides a directional charge-transfer channel to increase the utilization of photoinduced charge carriers. Moreover, the active species ( • O 2 –, h +, and 1 O 2 ) produced by IDT-COOH/O–CN under visible light play important roles in photocatalytic disinfection. The optimum 40% IDT-COOH/O–CN can kill 7-log of methicillin-resistant Staphylococcus aureus (MRSA) cells in 2 h and remove 88% tetracycline (TC) in 5 h, while O–CN only inactivates 1-log of MRSA cells and degrades 40% TC. This work contributes to a promising method to fabricate all-organic g-C 3 N 4 -based S-scheme heterojunction photocatalysts with a wide range of optical responses and enhanced exciton dissociation.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
