Catalytic Ammonia Synthesis over Mo Nitride/ZSM‐5
Bibliographic record
Abstract
Abstract Molybdenum nitride species in HZSM‐5 are prepared by the reaction of ammonia with MoO x , which is pre‐exchanged into the channel of HZSM‐5. Both the processes of solid exchange of molybdenum oxide with the zeolite and the ammonia reaction are monitored by mass spectrometry. The Mo/N ratio of the MoN x species in the Mo nitride/HZSM‐5 is close to 2, as measured by temperature‐programmed oxidation. The MoN x species are more stable than bulk Mo 2 N against oxidation, due to the interaction between the molybdenum nitride species and the charged zeolite framework. The MoN x species, of which the dispersion is found to be greater than 90 %, are very active in ammonia synthesis and the catalytic activity is much more stable than that of bulk Mo 2 N. The reaction pressure is much more favorable to ammonia formation on the MoN x /ZSM‐5 catalyst than on bulk Mo 2 N. The interaction of nitrogen molecules with the inner electric field of the zeolite, at an equivalent pressure, enhances the reaction of 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.
