Preparation and Characterization of Non-Precious Metal Fuel Cell Catalysts via Chemical Modification of Carbon Surfaces
Bibliographic record
Abstract
Preparation of non-precious metal catalysts (NPMCs) via chemical surface modification of carbon black with 5,6-diamino-1,10-phenanthroline (aphen) was completed. A diazonium coupling reaction was used to covalently attach aphen to the carbon surface and ratios of aphen to carbon were varied. The impact of this loading on the oxygen reduction reaction (ORR) was investigated. Cyclic voltammograms (CVs) were obtained under nitrogen to assess the redox activity of the phenanthroline type groups on the surface. Peaks at approximately 611 mV versus standard hydrogen electrode appear for each material and become larger with increased loading of aphen. Introduction of iron followed by pyrolysis at 700 °C results in increased activity towards the ORR and decreased hydrogen peroxide production.

How this classification was reachedexpand
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.
