Abstract
Abstract In this article, we report a one‐pot synthesis strategy to directly synthesize the hierarchical FeCu‐ZSM‐5 zeolite. Its physicochemical properties were studied by various characterization techniques and catalytic performance was tested in selective catalytic reduction (SCR) of NO with NH 3 as reductant. The characterization results show that: compared with three reference zeolites Fe/ZSM‐5, Cu/ZSM‐5, and Fe/Cu/ZSM‐5 prepared through an incipient wetness impregnation method, the synthesized FeCu‐ZSM‐5 zeolite exhibits hierarchical micro‐mesoporous structures, more Fe 3+ in zeolite framework, and larger isolated Cu 2+ species. Therefore, when used as a catalyst in NH 3 ‐SCR, the resulting hierarchical FeCu‐ZSM‐5 catalyst shows better catalytic performance (high NO conversion and N 2 selectivity) in a wide temperature window and higher hydrothermal stability than the three reference catalysts. Our work provides a simple and facile route to prepare the promising NH 3 ‐SCR catalyst for practical applications in controlling NO x emissions.

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 it
