Crossed PtCoCu Alloy Nanocrystals with High‐Index Facets as Highly Active Catalyst for Methanol Oxidation Reaction
Bibliographic record
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 machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
