Conductive Polymer-Titania Photocathode Development for Hydrogen Production
Bibliographic record
Abstract
Polybithiophene and polybithiophene-titania films were electropolymerized under galvanostatic conditions on carbon fibre paper substrates and tested under AM1.5G conditions in 0.5 mM H2SO4 in order to evaluate their catalytic performance, their photonic conversion efficiency, as well as their Faradaic photoelectrochemical performance for hydrogen generation. The electrochemical data indicates that the films were stable and showed promise as a viable photocathode material as they significantly reduced the cathodic overpotential needed to promote hydrogen generation up to a current density of 75 µAcm-2. The photonic efficiency was low and showed a maximum incoming photonic conversion efficiency (IPCE) at a current density of 240 µAcm-2. Substrate considerations such as sub-micron architectural variables should be further investigated alongside film thickness and nanoparticle composition to optimize the photonic and catalytic performance.

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.
