Nanocrystalline Ir{sub x}Sn{sub (1-x)}O{sub 2} electrocatalysts for oxygen evolution in water electrolysis with polymer electrolyte -- Effect of heat treatment
Bibliographic record
Abstract
Production and characterization of electrocatalysts for the oxygen evolution reaction in proton exchange membrane water electrolysers are described, with emphasis on the effect of the oxidizing or annealing temperatures on the properties of iridium/selenium oxide (Ir{sub 0}.6Sn{sub 0}.4O{sub 2}) nanocrystalline powders. Characterization of the synthesized powders was carried out using X-ray diffraction and electrochemical methods such as cyclic voltammetry and AC impedance. Results showed variation in the properties of these materials within the temperature range examined, the main differences relating to the crystallization and stability of the oxides. Best performance at low current was achieved when the material was oxidized at 450 degrees C for 30 minutes. More analysis was suggested to confirm the stability and structure of these materials and to determine how they perform in polymer electrolyte-based systems. 33 refs., 2 tabs., 9 figs.

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.
