Photochemical Route for the Preparation of Complex Amorphous Water Oxidation Catalyst
Bibliographic record
Abstract
A photochemically initiated decomposition reaction was used to synthesize a series of amorphous mixed-metal oxide films. The series, consisting of mixed-metal oxides included binary and ternary mixtures containing Fe, Co and/or Ni, enabled a systematic evaluation of amorphous metal oxides with complex compositions. X-ray diffraction results indicate that the as-deposited films are amorphous and can be converted to their crystalline form by heating. Infrared spectroscopy of the films indicates the photochemically driven process drives complete loss of the organic constituents from the film. X-ray photoelectron spectroscopy confirmed the loss of the organic ligand and enabled estimation of metal oxidation states. Electrochemical characterization revealed significant variation in catalytic performance toward the oxygen evolving reaction (OER) upon variation of metal oxide composition. Analysis of the Tafel behavior was used to distinguish amorphous mixed-metal oxide films to enable several film compositions to exhibit excellent electrocatalytic OER performance.

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.
