Preparation and Electrochemical Characterization of Ordered Mesoporous Carbon/PbO Host-guest Composite Electrode Materials for Supercapacitor
Bibliographic record
Abstract
Ordered mesoporous carbon/PbO host-guest composites were prepared by incipient wetness impregnation method. The XRD, TEM and N2 adsorption/desorption isotherms tests confirm the host-guest structure of the composites. The PbO loading amount affects the structure and electrochemical properties of the composites and the optimum amount of Pb (NO3)2 added is found to be 60 % of that of the saturated solution. Besides, the specific capacitance of the composite (83 F g-1) is more than twice of that of the pristine PbO (37 F g-1) at the scan rate of 5 mV s-1 and is more or less equal to that of the ordered mesoporous carbon at the scan rate of 200 mV s-1 (the specific capacitance of the composite is 58 F g-1), demonstrating excellent rate capability. Furthermore, the composite electrode material shows a stable cycle life in the potential range of 0-0.9 V after 500 cycles.

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.
