A Quantitative Study of Hydroxyl Radical Production on a Ti/SnO<sub>2</sub>-Sb<sub>2</sub>O<sub>5</sub> Anode
Bibliographic record
Abstract
A nitroso compound (R-NO) known as a “spin trap” was used to study the production of hydroxyl radicals (OH·) on a Ti/SnO 2 -Sb 2 O 5 anode. A linear voltammetry study was conducted on this anode in the presence of this compound, using the rotating disk electrode technique. The results showed that the electrode started to produce (OH·) at 0.7V vs. Ag/AgCl reference electrode. The current was limited by the mass-transport of RNO in the electrolyte. When the voltage increased to 1.4V and higher, significant oxygen evolution took place. Further investigation was conducted by constant voltage electrolysis and spectroscopic measurement of the RNO concentration. The change in the RNO was interpreted as the evolution of (OH·), and the current efficiency was calculated based on the assumed stoichiometry. The results showed that the efficiency was optimal within the potential range 0.7-1.4V, and the highest efficiency could reach 30%. This was in agreement with the RDE experiment.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
