Abstract
Abstract Nanocrystals with high‐index facets are arousing growing attention in terms of rational design of efficient electrocatalysts. Herein, ternary PtCoCu alloys with distinct crossed and dendritic structure are prepared via one‐pot approach simply by tuning the amount of serine. The electrocatalytic performances for methanol oxidation reaction by these PtCoCu alloys are examined. It turns out that the {hk0} high‐index facets‐covered surfaces endow the crossed PtCoCu alloy with 4.2‐fold improvement of specific activity relative to commercial Pt/C and with superior stability. This work provides a facile and feasible route for synthesizing tri‐ or multimetallic alloys for electrocatalytic applications.

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 it
