H[sub 2]O[sub 2] Release during Oxygen Reduction Reaction on Pt Nanoparticles
Bibliographic record
Abstract
The impact of 3M's nanostructured thin film electrocatalyst loading on rotating ring-disk electrode (RRDE) experiments for the oxygen reduction reaction (ORR) in a solution has been studied. The electrocatalysts were prepared by sputtering Pt onto support whiskers and have been reported to exhibit one of the best specific activities of any ORR catalyst thus far. However, a dramatic increase in release was observed as the catalyst loading (number of catalyzed whiskers per unit area) on the glassy carbon tip of RRDE was decreased below , confirming some earlier observations reported by our group and other research groups with some other types of catalysts. These observations suggest that oxygen reduction occurs through a intermediate, and if the catalyst nanoparticles are sparsely distributed, the produced cannot be efficiently reduced to before it escapes. Similar observations have been made for and Fe–N–C catalysts.

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.
