Directed Growth of a Bimetallic MOF Membrane and the Derived NiCo Alloy@C/Ni<sub><i>x</i></sub>Co<sub>1‐<i>x</i></sub>O/Ni Foam Composite as an Efficient Electrocatalyst for the Oxygen Evolution Reaction
Bibliographic record
Abstract
Abstract Hierarchically structured bimetallic NiCo‐MOF/LDH/Ni foam (NiCo‐MOF/LDH/NF; MOF=metal−organic framework, LDH=layered double hydroxides) composites were successfully fabricated by means of the in situ growth of NiCo‐MOF on the NiCo LDH buffer‐layer‐modified NF surface. After carbonization, the derived NiCo alloy@C/NixCo1‐xO/NF hierarchical nanocomposite showed excellent electrocatalytic activity with respect to the oxygen evolution reaction (OER); specifically, it exhibited a very low overpotential of 300 mV at a current density of 100 mA cm−2. The outstanding OER activity of the composite may be attributed to the open structure of the nanocomposite, the formation of the highly dispersed CoNi alloy, and the synergistic interaction between CoNi@C and NixCo1‐xO. This work introduces a new strategy for constructing advanced hierarchically structured nanocomposites for diverse applications.

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.
