Abstract
Abstract The regulation of geometric and electronic structures is very important to transition metal phosphides with high catalytic properties. Herein, nanofilms consisting of NiCoFeP nanospheres were electrochemically deposited onto 3D Ni foam for the catalysis of water splitting. Depending on the amount of iron, the NiCoFeP nanocatalysts exhibit different surface topographies and chemical binding energies, which have a great influence on electrochemical performances. The optimal NiCoP‐0.01 M Fe films show robust bifunctional electrocatalytic activities with an overpotential of 118 mV (10 mA cm −2 ) for the hydrogen evolution reaction (HER) and 300 mV (50 mA cm −2 ) for the oxygen evolution reaction (OER). The overall water splitting employing this proposed nanocatalyst at both electrodes only presents a cell voltage of 1.60 V at the current density of 10 mA cm −2 , far lower than that (1.73 V) with the commercial Pt/C cathode and RuO 2 anode combination.

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
