Light Enhanced Water Dissociation in Bipolar Membranes
Bibliographic record
Abstract
Abstract Bipolar membrane (BPM) integration can allow robust and abundant materials to be implemented into energy conversion frameworks and purification pathways vital for the development of clean technologies. However, large membrane voltages associated with water dissociation (WD) have hampered widespread adoption. This work investigates an alternative method to reduce the overvoltage associated with WD operation by illuminating the BPM interface in the presence of nanoparticulate catalyst layers that exhibit plasmonic character. The plasmonic character of the catalyst enhanced the field locally near the active catalyst site, lowering the resistance associated with WD as well as the onset potential for WD. Optimal catalyst loadings allowed a balance of light absorption, catalyst activity, and field utilization. Composites of known WD catalysts that exhibited minimal light activity with a plasmonic and WD active material exhibited improvements in the WD resistance and overvoltage of up to 20 % upon irradiation. This proof‐of‐concept work introduces a new paradigm for altering WD activity in BPMs, where the optical activity of WD catalysts can provide further tunability towards efficient WD and alternative energy conversion frameworks.

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.
