“…Spinel-structured NiCo 2 O 4 , a classical Ni–Co binary metal oxide, represents the superior OER candidate for their adjustable electronic structures and high stability in alkaline electrolytes . Great efforts have been executed on the NiCo 2 O 4 -based electrocatalyst to further improve the OER activity, such as heteroatom doping, nanostructuring, or recombining heterostructures. − …”

Hierarchical nanostructures with unique synergistic electronic effects and abundant active sites play an essential role in the field of electrocatalysis. In this work, 1D@2D hierarchical NiCo 2 O 4 @MIL-53(Fe) nanostructures are constructed via introducing MIL-53(Fe) over NiCo 2 O 4 nanoneedles grown on nickel foam [NiCo 2 O 4 @MIL-53(Fe)]. NiCo 2 O 4 @MIL-53(Fe) exhibits high catalytic activity of the oxygen evolution reaction due to the strong electronic interaction between NiCo 2 O 4 and MIL-53(Fe), as well as the hierarchical nanostructures that provide numerous active sites. In 1.0 M KOH, the NiCo 2 O 4 @MIL-53(Fe) can achieve the current densities of 10 and 100 mA cm −2 with overpotentials of only 231 and 260 mV, respectively; the hierarchical catalysts show good electrochemical and structural stability, operating for more than 100 h at a current density of 10 mA cm −2 without obvious decay.
