Abstract
Abstract The high cost of preparation of transition metal doped ZSM‐5 zeolite is limited to the use of organic template such as tetrapropylammonium hydroxide or tetrapropylammonium bromide. In this work, vanadium atom was successfully incorporated into the framework of ZSM‐5 zeolite without using any organic template. Moreover, the method not only decreases the preparation cost of vanadium doped ZSM‐5, but also greatly enhances the utilization ratio of vanadium atom. Vanadium atom mainly exists as tetrahedral coordination in the framework of ZSM‐5 which was demonstrated by the ultraviolet visible and X‐ray photoelectron spectrum. Furthermore, vanadium doped ZSM‐5 performs high and stability catalytic activity in the oxidation of styrene compared to that of the catalyst prepared by the traditional organic template method ascribe to the greatly increase of tetrahedral vanadium species.

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
