Using an interface engineering strategy, we successfully synthesized a core-shell nano-flower array of CuCo₂O₄/NiFe-layered bimetallic hydroxide (LDH) on nickel foam (NF) (CuCo₂O₄/NiFe-LDH@NF). The research indicates that electrons undergo transfer across the coupled interface of CuCo₂O₄ and NiFe-LDH, resulting in the enrichment of the CuCo₂O₄ core in electron density and thereby enhancing reaction kinetics. The amorphous NiFe-LDH shell not only provides additional channels for electron/material transport and increases active sites but also effectively shields the core CuCo₂O₄ from strong alkali corrosion during the oxygen evolution reaction (OER) in electrocatalysis. Therefore, when employed as an OER catalyst in a 1.0 mol·L^-1 KOH solution, CuCo₂O₄/NiFe-LDH@NF required only a low overpotential of 191 mV to achieve a current density of 10 mA·cm^-2 and a low Tafel slope of 31 mV·dec^-1. Furthermore, CuCo₂O₄/NiFe-LDH@NF demonstrated stability in catalytic performance, crystal structure, morphological structure, and composition during prolonged operation.
