One‐Dimensional<scp>Pt</scp>Nanostructures for Polymer Electrolyte Membrane Fuel Cells
Bibliographic record
Abstract
This chapter discusses the achievements on the controlled synthesis of different shaped platinum (Pt) nanostructures with uniform size and shape distribution through several approaches. The synthetic challenge is to develop approaches to those predetermined nanostructures with high-level controls of uniformity in size, shape, and composition if Pt alloys are desired. The chapter also discusses the influence of different shapes of Pt nanostructures on the kinetics of both cathodic and anodic reactions relevant for polymer electrolyte membrane fuel cells (PEMFCs). It analyses some of the important parameters such as surface area, exposure crystallographic planes, density of atomic steps, and kinks responsible for this shape-dependent electrocatalytic behavior. The chapter focuses on the syntheses of one-dimensional (1D) Pt nanowires and nanotubes and their use as electrocatalysts in PEMFCs. The carbon-supported Pt nanowires could be readily processed as electrocatalysts for fuel cell applications.

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.
