ZIF-Derived CuPt@Ag as Catalyst for Hydrogen Evolution Reaction
Bibliographic record
Abstract
In this study, ZIF-Cu and ZIF-Pt were synthesized from 2-methyl imidazole with Cu and Pt salts in the methanol medium. The synthesized ZIFs were annealed to produce a CuPt nanocatalyst in the tube furnace. The Cu: Pt (3:1) nanocatalyst slurry was deposited on silver deposited carbon rod electrode (CE). The hydrogen evolution reaction (HER) activities for the catalyst were measured in a 1 M KOH solution by using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. The morphological structure and composition of CuPt@Ag have been studied by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDX). It was observed that the prepared electrode surface had not only a homogeneous and porous structure but also nano-sized particles distributed on the surface. It has been observed that the current is increased from 5.22 mA cm-2 to 25.80 mA cm-2 under -1.55 V potential at CuPt@Ag electrode. The high current density shows that HER efficiency increases on the prepared catalyst.

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.
