Co-C-N Oxygen Reduction Catalysts Prepared by Combinatorial Magnetron Sputter Deposition
Bibliographic record
Abstract
Thin film libraries of CoxC1-x-yNy (0 < x < 0.106, 0.003 < y < 0.190) have been prepared by combinatorial magnetron sputter deposition and subsequent heat-treatment at 700, 800 and 1000{degree sign}C in N2. Libraries with 0 < x < 0.105 and 0.026 < y < 0.096 heat-treated at 800{degree sign}C show good catalytic activity towards the oxygen reduction reaction (ORR) in 0.1M HClO4 solution at room temperature. The catalytic activity of the CoxC1-x-yNy libraries is strongly dependent on the heat-treatment temperature. Heat-treated CoxC1-x-yNy libraries show good stability against Co dissolution in 0.5M H2SO4 at room temperature, suggesting that catalysts stable in the PEM fuel cell environment can be found.

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.
