Synthesis of Cobalt Sulfide/Sulfur Doped Carbon Nanocomposites with Efficient Catalytic Activity in the Oxygen Evolution Reaction
Bibliographic record
Abstract
Abstract Cobalt sulfide/sulfur doped carbon composites (Co 9 S 8 /S‐C) were synthesized by calcining a rationally designed sulfur‐containing cobalt coordination complex in an inert atmosphere. From the detailed transmission electron microscopy (TEM) and X‐ray photoelectron spectroscopy (XPS) analyses, the electrocatalytically active Co 9 S 8 nanoparticles were clearly obtained and combined with the thin sulfur doped carbon layers. Electrochemical data showed that Co 9 S 8 /S‐C had a good activity and long‐term stability in catalyzing oxygen evolution reaction in alkaline electrolyte, even better than the traditional RuO 2 electrocatalyst. The excellent electrocatalytic activity of Co 9 S 8 /S‐C was mainly attributed to the synergistic effect between the Co 9 S 8 catalyst which contributed to the oxygen evolution reaction and the sulfur doped carbon layer which facilitated the adsorption of reactants, prevented the Co 9 S 8 particles from aggregating and served as the electrically conductive binder between each component.

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.
