The photocatalytic activity of nano-TiO_2 powder with mixed crystal structure
Bibliographic record
Abstract
The nano-TiO2 powders of mixed crystal structure were prepared and charactered. The relationship between the crystal structure and its photocatalytic activity was investigated. The results show that photocatalytic activity of TiO2 was reduced firstly, when the mass percent of rutile phase was less 18.53%. When the mass fraction of rutile phase was in the range from 18.53% to 28.2%, the activity of TiO2 was promoted. The TiO2 powder contained 28.2% rutile phase was most active and degraded 97% Rhodamine B in 60 min. When the mass percent of rutile phase exceeded 28.2%, the catalytic activity reduced renewedly. The existence of rutile phase in definite quantity favors the charge seperation and promote the photocatalytic activity.

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.
