Abstract
Abstract Hierarchical zeolite ZSM‐5 has attracted enormous attention due to its shape selectivity in catalytic process. However, sustainably obtaining zeolite ZSM‐5 in a completely inorganic synthesis system is still a great challenge. In this study, a facile and inorganic strategy to manipulate the mesopore structure was reported. Taking advantage of grafted Mg species as the source of defect sites, the resultant ZSM‐5 was demonstrated to have a total BET surface area of 363.6 m 2 · g −1 , and a mesoporous surface area of 156.2 m 2 · g −1 . Moreover, the hierarchical material showed much enhanced catalytic cracking activity for heavy oil due to its micro‐mesoporosity structure. This strategy opens a novel way for the green obtaining of zeolites with hierarchical structure.

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.
