Electrochemical Synthesis of Ammonia in Molten Salt Electrolyte Using Hydrogen and Nitrogen at Ambient Pressure
Bibliographic record
Abstract
In this study, the synthesis of ammonia (NH3) at ambient pressure using H2 and N2 is electrochemically achieved. The conducting and reaction media with molten salt consist of molten hydroxide as NaOH and KOH whereas the reaction temperature is varied in the range of 200°C to 255°C to investigate the impact of temperature on the ammonia production rate and hence performance. The porous nickel mesh electrodes having an area of 100 cm2 are used as cathode and anode where the supplied electricity is controlled using potentiostat/galvanostat. The maximum faradaic efficiency for ammonia synthesis is found to be 9.3% at 210°C corresponding to 6.53 × 10−10 mol/s cm2 ammonia evolution rate at 2 mA/cm2 current density with nano-Fe3O4 as the catalyst. Furthermore, the applied voltages and applied currents are varied to find the optimum experimental conditions for molten salt electrolyte based electrochemical ammonia synthesis.

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.
