Abstract
Strong electronic coupling between graphene quantum dots (GQDs) and graphitic carbon nitride (g‐C 3 N 4 ) enables multiple charge transfer pathways, offers a new approach for light harvesting, and opens novel applications for carbon‐based materials. Herein, a nitrogen‐doped graphene quantum dots (NGQDs)/g‐C 3 N 4 composite is designed by stitching NGQDs with g‐C 3 N 4 through a thermal condensation approach, which conjugate via NGQDs‐lone pair electrons in a ternary N‐g‐C 3 N 4 nanosheet (π–p–π) network. It is found that the H 2 evolution rate under visible light ( λ ≥ 420 nm) irradiation with NGQDs/g‐C 3 N 4 is nearly 7.7, 7.2, and 2.5 times higher than that of pristine g‐C 3 N 4 , the mixture of NGQD and g‐C 3 N 4 , and a non‐nitrogen‐doped GQDs/g‐C 3 N 4 composite, respectively. Due to better light harvesting in the NGQDs/g‐C 3 N 4 composite, higher photocatalytic activities are also observed compared to others when they are illuminated by 520 and 550 nm light. It is demonstrated that the electronic coupling between NGQDs and g‐C 3 N 4 generates new bands, driving the charge transfer along the π–p–π network and extending the visible light response range.

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 it
