Sulfur Vacancy and V-Doped CoP-Modulated 3D Zr-MOF (UiO-66-NH<sub>2</sub>)/2D MoS<sub>2</sub> Interface Restructuring for Efficient and Durable Hydrogen Evolution Reaction
Bibliographic record
Abstract
An integrated Zr-based MOF/MoS 2 (UiO-66-NH 2 /MoS 2 ) electrode was synthesized via a one-step hydrothermal in situ method for electrocatalytic hydrogen production. By leveraging the synergistic properties of UiO-66-NH 2 and MoS 2, the improvement of active site accessibility, conductivity, and electrochemical response was achieved. Sulfur vacancy engineering induced the restructuring of electrode composites, thereby improving the electrocatalytic activity and stability of the integrated electrodes. Modification of the UiO-66-NH 2 /MoS 2 electrode through the electrodeposition of vanadium-doped cobalt phosphate (VCoP) demonstrated further enhancement on hydrogen evolution reaction with a current density of 3 mA/cm 2 at 0.95 V, with a low overpotential of 25.74 mV dec –1 in 0.5 M H 2 SO 4 . The doping effects of V 3+ and Co 2+ facilitated charge separation and interfacial charge transfer with enhanced stability, attributed to the improved physicochemical interaction within the restructured electrode architecture.

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.
