Morphology controllable growth of Pt nanoparticles/nanowires on carbon powders and its application as novel electro-catalyst for methanol oxidation
Bibliographic record
Abstract
Pt nanowires (PtNWs) have been controllably synthesized on carbon powders by the reduction of H(2)PtCl(6) with HCOOH. By adjusting the pH value of the solution, PtCl(6)(2-) can be controllable reduced into particles or nanowires. The Pt nanowires are single crystals growing along the <111> direction with a diameter of 3 nm and a length of 10 nm. The dispersion of Pt nanowires on the surface of carbon powders can be controlled by changing the loading of Pt. The PtNWs/C is evaluated as the catalyst for methanol oxidation. The PtNWs/C with 20 wt% Pt has a larger electrochemical active surface area and much higher mass activity for methanol oxidation than that of commercial Pt/C catalyst. The PtNWs/C catalyst shows significant improvement in the kinetics for methanol oxidation and mass transfer property due to the single crystal structure of the Pt nanowires. The PtNWs/C catalyst holds promising potential applications in energy converting devices and environmental protection.

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.
