Hexagonal petal-like cobalt oxide nanowire arrays encapsulated by MOF-derived Co/N-codoped carbon for boosting electrochemical capacitor behaviour

Abstract

A novel core–shell hetero-structured electrode (NF@CoO@Co/N–C) is designed and synthesized via a “anchor-etch-calcine” process for boosting electrochemical capacitor behaviour. The unique structure endows NF@CoO@Co/N–C with ultrahigh areal capacitances and good rate capability.
