Abstract

fetched live from OpenAlex

MoO3SiO2 (MoSiO) surface complex supports were prepared by surface modification PdCu bimetallic catalysts were prepared by incipient impregnation BET, TPR and IR techniques have been used to investigate the structure of catalysts and chemisorption states of CO2 and C3H8 Horizontal type chemisorption of CO2 is found; C3H8 is chemisorbed on terminal O of Mo=O bond through H of methylene and one of methyl The catalysts were tested in the reaction of oxidative dehydrogenation of propane with carbon dioxide to propene in a microreactor In the condition of ambient pressure and 600℃, the conversion of propane was 2694%, and the selectivity of propene was 7834% By relating the physical and chemical characters of catalysts with their performance in reaction, a reaction mechanism was proposed and the factors which influence the activity of the catalysts were also studied

Full frame distilled prediction

Teacher imitation

Not 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.
