Pd Nanoparticles Coupled to WO<sub>2.72</sub> Nanorods for Enhanced Electrochemical Oxidation of Formic Acid
Bibliographic record
Abstract
We synthesize a new type of hybrid Pd/WO 2.72 structure with 5 nm Pd nanoparticles (NPs) anchored on 50 × 5 nm WO 2.72 nanorods. The strong Pd/WO 2.72 coupling results in the lattice expansion of Pd from 0.23 to 0.27 nm and the decrease of Pd surface electron density. As a result, the Pd/WO 2.72 shows much enhanced catalysis toward electrochemical oxidation of formic acid in 0.1 M HClO 4; it has a mass activity of ∼1600 mA/mg Pd in a broad potential range of 0.4–0.85 V (vs RHE) and shows no obvious activity loss after a 12 h chronoamperometry test at 0.4 V. Our work demonstrates an important strategy to enhance Pd NP catalyst efficiency for energy conversion reactions.

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.
