Pt Hollow Nanospheres as an Electrocatalyst for the Oxygen Reduction Reaction
Bibliographic record
Abstract
Pt hollow nanospheres (HNSs) were deposited uniformly on commercial Vulcan XC-72R (VC) and explored as an electrocatalyst for the oxygen reduction reaction (ORR) in PEMFCs. VC-supported Pt HNSs have a uniform Pt HNS particle size of ca. 18 nm and a homogeneous particle distribution on the support. The Pt HNSs consist of discrete Pt nanoparticles (NPs) with a crystallite size of ca. 2-3 nm. Compared with its counterpart Pt(20 wt%)NP/VC the as-synthesized Pt(20 wt%)HNS/VC has demonstrated a considerable enhancement in the mass activity towards the ORR because of its unique nanostructure and the contribution from alloying of Pt with Co.

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.
