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.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
