Selective Dibenzothiophene Adsorption on Graphene Prepared Using Different Methods
Bibliographic record
Abstract
Graphite oxide synthesized with phosphoric acid, labeled “GOP”, shows a higher degree of oxidation and has a larger interlayer spacing than the oxide prepared using the conventional Hummers method, referred to as “GOH”, as confirmed by X-ray photoelectron spectroscopy and X-ray diffraction analyses. This study was performed under the assumption that the oxygen-containing functional groups between the GOP layers are more easily reduced than those between the GOH layers. Raman analysis supported this assumption in that the reduced graphene from GOP has a larger number of sp 2 carbons and fewer defects than the graphene obtained from GOH. The relative extent of defects in graphene can be investigated by dibenzothiophene (DBT) adsorption, which requires π–π interactions between the free π-bonds of sp 2 atoms from graphene and those from the aromatic ring of DBT. The graphene obtained from GOP showed higher DBT adsorption capacity than that synthesized from GOH. In addition, the DBT adsorption capacity on graphene decreased as the concentrations of other aromatic compounds increased.

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.
