Bio‐Inspired Self‐Activating Polydimethylsiloxane‐Modified CrO<sub><i>x</i></sub>/Al<sub>2</sub>O<sub>3</sub> Catalyst for Acetylene Semihydrogenation
Bibliographic record
Abstract
Abstract Biomimetic approach is a nature‐driven strategy for designing functional materials to meet the industrial challenges. Here we demonstrate the bio‐inspired discovery of a self‐activating catalyst, with polydimethylsiloxane anchored over the surface of CrO x /Al 2 O 3 , exhibiting comparable performance with noble metallic catalysts for acetylene semihydrogenation. In addition, the dynamic movement of polymer chains with high flexibility renders the catalyst to impose proactive perturbation to the undesired coke precursors generated in reaction, analogous to the function of hair‐like cilia on the surface of respiratory epithelial cells, thus avoiding the site‐blocking induced by carbonaceous deposits and sustaining the catalyst stable for 1000 h without any deactivation. This study paves the way to develop other heterogeneous catalysts with high efficiency and durability via mimicking the innate defense mechanism of natural organisms.

How this classification was reachedexpand
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.
