Effect of nitrogen doping on the catalytic activity of activated carbon and distribution of oxidation products in catalytic wet oxidation of phenol
Bibliographic record
Abstract
Abstract Nitrogen‐containing functional groups were introduced into activated carbon (AC) by amination at high temperatures to investigate their effects on the catalytic activity and distribution of products in the catalytic wet air oxidation (CWAO) of phenol at 120 and 160 °C. The results show that the catalytic activity of the nitrogen‐doped AC increases with amination temperature from 250 to 850 °C. The linear relationship between the quantity of nitrogen‐containing functional groups and the catalytic activity indicates that the enhanced activities are closely related to the amount of pyridinic and pyrrolic nitrogen groups on the surface of the AC. The parent and aminated AC exhibit distinct distributions of oxidation products. Oxalic acid is favourably degraded on the aminated AC, whereas the all‐carbon AC shows a similar ability for the removal of acetic acid.

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.
