A hierarchical CuO@NiCo layered double hydroxide core–shell nanoarray as an efficient electrocatalyst for the oxygen evolution reaction
Abstract
A hierarchical CuO@NiCo LDH core–shell nanoarray on copper foil (CuO@NiCo LDH/CF) acts as an efficient and durable oxygen-evolving electrocatalyst, capable of driving 20 mA cm −2 at an overpotential of only 256 mV in 1.0 M KOH.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
