Bipolar electrochemical deposition of HKUST‐1 on carbon and its loading with polypyrrole for supercapacitor electrodes
Bibliographic record
Abstract
Abstract Using bipolar electrochemistry, carbon paper (CP) is asymmetrically coated with copper metal. Subsequent anodic electrodissolution in a solution containing trimesic acid linkers results in HKUST‐1 depositing on the carbon surface. The CP‐MOF (metal organic framework) composite is then soaked in a pyrrole/isopropanol solution for several hours before undergoing oxygen/Cu‐induced polymerization to fill the pores. Variations in the concentration and soaking time were investigated. X‐ray diffraction shows the successful synthesis of HKUST‐1 before and after pyrrole treatment. Scanning electron microscopy and optical microscopy suggest that the polymer is formed within HKUST‐1 rather than as a coating. Further characterization by Fourier transform infrared, X‐ray photoelectron spectroscopy, gas adsorption, and thermogravimetric analysis/differential thermal analysis were also carried out. Capacitance was found to increase with the concentration of pyrrole used to load HKUST‐1. Higher concentrations also lead to more leaching of copper. Differential pulse voltammetry (DPV), galvanostatic charge discharge, and electrochemical impedance spectroscopy electrochemically studied the redox peaks, capacitance retention, and resistivity of the electrodes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
