Abstract
Graphitic carbon nitride (g‐CN) is a promising photocatalyst for solar fuel generation due to its medium band gap and facile synthesis from earth‐abundant materials. However, low charge carrier mobility and high charge recombination have hampered the observed rate of H 2 evolution and CO 2 reduction. Herein, an electrostatically self‐assembled 2D Z‐scheme heterojunction between g‐CN and bismuth vanadate (BiVO 4 ) is investigated with and without reduced graphene oxide (rGO) acting as an electron transfer mediator to speed charge carrier mobility and hamper charge recombination. Protonation of the g‐CN surface allow for self‐assembly between 2D sheets of g‐CN, rGO, and BiVO 4 . The mass ratio between g‐CN and BiVO 4 is incrementally adjusted to optimize synergistic charge transportation effects versus shadowing effects of multicomponent photocatalysts. Further, a selectivity effect is observed across mass ratios of photocatalyst constituents, allowing tuning of photocatalyst yield.

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
