Mo<sub>2</sub>C-MoS<sub>2</sub> heterojunction a suitable and stable electrocatalyst for HER and supercapacitor Applications
Bibliographic record
Abstract
Abstract In the present work, Mo2C-MoS2 heterojunction structures have been prepared by the wet impregnation method. For heterojunction species, the content of MoS2 was varied from 5 to 20% by weight. The effect of the loading content of MoS2 over Mo2C on hydrogen evolution reaction (HER) activity and electrochemical (EC) capacitance performance has been studied in detail. The Mo-C-S junction plays a key role in enhancing the HER activity and EC capacitance performance than the individual components. The prepared structures show enhanced HER activity with high current density ~36.2-78.3 mAcm-2 at very low applied potential (0.45 V), exhibiting a lower Tafel slope of 102.4 mVdec-1. The EC capacitor performance determined by CV and galvanic charge-discharge (GCD) reveals that the synthesized samples exhibit an electrochemical double-layer capacitor (EDLC, Cdl) behavior. The higher EDLC (43.9 mFcm-2) and specific capacitance (2Fg-1) obtained for the synthesized samples determine their potential applicability for the new generation supercapacitors.

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.
