Highly Active Sites in Quaternary LnPdAsO (Ln = La, Ce, Pr) with Excellent Catalytic Activity for Hydrogen Evolution Reaction
Bibliographic record
Abstract
We report the catalytic activity in LnPdAsO (Ln = La, Ce, Pr). In this PdAs– layer (II), by elongating the distance of Pd–Pd, the overpotentials toward HER are 110.0, 89.5, and 62.0 mV at 10 mA/cm2 for PrPdAsO, CePdAsO, and LaPdAsO, respectively. Furthermore, the Tafel slope and robust long-term stability in LaPdAsO even surpasses the capability of optimized Pd and Pd/C. Density functional theory calculations reveal that the active sites lie at the center of Pd–’s net with a free energy barrier of 0.09 eV for H–H reaction. The present engineering two-dimensional Pd provides a route for exploring superior electrocatalyst on the basis of known noble metals.

How this classification was reachedexpand
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.
