Nanostructured Pt Surfaces with Ir Submonolayers for Enhanced NH<sub>3</sub> Electro‐oxidation
Bibliographic record
Abstract
Abstract Preferentially (100)‐oriented nanostructured platinum films were modified by subsequent surface functionalization with iridium through pulsed electrodeposition. The Ir surface coverage was adjusted by varying the number of applied electrodeposition pulses, and was found to modify the reactivity towards NH 3 oxidation. Deposition of minute amount of Ir atoms ([Ir]=6 at%) at the surface of preferentially (100)‐oriented Pt leads to a decrease in the NH 3 oxidation onset potential (from −430 to −500 mV vs. Hg/HgO), an increase in the current density (at −0.30 V) from 0.55 to 0.67 mA cm −2 , and an increase in the poisoning resistance over polarization at constant potential. This is attributed to the preferential adsorption of Ir atoms at Pt(100) step sites close to the Pt(100) terraces that are known to be the more active for the electro‐oxidation of NH 3 .

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.
