Metal–Organic Framework Templated 3D Hierarchical ZnCo₂O₄@Ni(OH)₂ Core–Shell Nanosheet Arrays for High‐Performance Supercapacitors

Designing core-shell electrode materials with desired components and architectures is a promising strategy for boosting electrochemical performance. Here, three-dimensional hierarchical ZnCo2 O4 @Ni(OH)2 core-shell nanosheet arrays have been successfully fabricated on a Ni foam substrate, in which the porous ZnCo2 O4 nanosheet "core" as the conductive scaffold was synthesized by a metal-organic framework (MOF)-templated method, and the ultrathin...
