Abstract
Abstract Asymmetric (Pt|Nafion|Pt–Pd–Cu) assemblies were fabricated to study the nitrate‐reduction reaction (NRR) at the cathode surface. The influence of the material composition, supplied current, and applied potential on the reactivity, kinetics, and product selectivity were thoroughly investigated. The cathode assembly consisting of 54 atom % Pt showed enhanced reactivity both in binary (Pt–Pd; k 1 ≈10.7×10 −3 min −1 ) and ternary (Cu–Pt–Pd; k 1 ≈28.6×10 −3 min −1 ) states. This composition was found to be highly nitrite‐selective (80 % in the binary state and 53 % in the ternary state). The mechanistic studies revealed that the reduction of nitrate ions to ammonia proceeded through a catalytic hydrogenation reaction followed by electrochemical hydrogen generation.

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
