Abstract
Sensitization of semiconductor material is well recognized in the field of photography and photo-electrochemistry. Recently, dye sensitization technique has found its application in solar cells. Dye sensitization can further be applied for water treatment and sacrificial hydrogen generation using photocatalysis. Success of the process depends on the choice of suitable dye, semiconductor material, electron donor, and light sources. Attachment of dye molecule on photocatalyst surface leads to subsequent electron transfer into the conduction band of semiconductor, therefore strongly bound anchoring groups are preferred. Fixation of dye molecule on semiconductor surface also improves the electron transfer process. Incorporation of noble metals on semiconductor surface enhances their photocatalytic activity by reducing the electron/hole recombination rate. Dye-sensitized photocatalyst is applied for degradation of a wide range of compounds such as i) aliphatic compounds (carbon tetrachloride, trichloroethylene, hydrazine, and pesticides), ii) aromatic compounds (non-sensitizing dye, phenol, chlorophenol, and benzyl alcohol) in aqueous medium. Hydrogen generation is also possible in visible light with dye-sensitized photocatalyst in presence of sacrificial reagents. Ruthenium based dyes in solar cells and dye-sensitized photocatalysis are the best reported so far, however, researchers are gradually switching towards inexpensive and environment-friendly organic dyes and/or natural dyes from vegetable sources. Eosin Y is an organic dye which has been widely used for hydrogen generation, reportedly providing quantum yields between 9-19 %.

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
