A bifunctional electrocatalyst based on NiCo-LDH ultrathin nanosheets grown on a nickel foam shows a superior overall water-splitting performance.
It is of great importance to construct non-precious metal bifunctional electrocatalysts with low cost and high efficiency for overall water splitting.
3D core–shell nanostructures of few-layer NiFe LDH nanosheets grown on Cu nanowires are fabricated toward highly efficient overall water splitting.
