Abstract
Graphitic carbon nitride (g‐CN) is a promising photocatalyst for solar fuel generation, but its charge carrier mobility, charge recombination, and CO 2 reduction/H 2 evolution efficacy and selectivity are a strong function of the synthesis and postsynthesis techniques employed. Protonation and phosphorous doping of g‐CN yield promise visible light activities, promoting enhanced CO 2 reduction and hydrogen evolution. However, the amine‐functionalized surface chemistry of g‐CN gains little attention in open literature. Herein, g‐CN and phosphorus‐doped g‐CN are synthesized via facile one‐pot pyrolysis and subjected to protonation postsynthesis to quantify the influence of common strategies on surface amine content and photocatalyst activity for H 2 evolution and CO 2 reduction. Material characterization confirms the exfoliation of the photocatalyst and change in the amine functionalization of the surface. The amorphous phosphorus‐doped g‐CN material exhibits a high number of surface amine groups, increasing the adsorption prior to reduction and enhancing selectivity for CO 2 reduction.

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
