Carbon/MoO<sub>2</sub> Composite Based on Porous Semi-Graphitized Nanorod Assemblies from In Situ Reaction of Tri-Block Polymers
Bibliographic record
Abstract
Ordered mesoporous carbon materials with a semi-graphitized structure have been synthesized by directly employing a tri-block copolymer as a structure directing agent and carbon source to form mesoporous carbon. Poly(ethylene oxide) 20 -poly(propylene oxide) 70 -poly(ethylene oxide) 20 (EO 20 PPO 70 EO 20 ), or “P123”, was cross-linked in the channels of mesoporous silicate, carbonized, and graphitized. Extraction of the silica produces a mesoporous graphitic carbon replica. The graphitization of carbon was realized by employing transition metals (Fe, Co, Ni) as a catalyst in a reducing atmosphere. Of the three transition metal catalysts, nickel was found to be the best candidate in terms of preserving structural order. All three nanoporous carbon materials have 3 orders higher conductivity and better thermal stability than non-graphitic carbon. A composite of ordered mesostructured carbon/metallic MoO 2 (63.7 wt % MoO 2 ) was prepared and examined as a negative electrode in a lithium rechargeable battery. The material exhibited a reversible capacity of 760 mA·h/g in the voltage window 3.0−0.0 V.

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.
