  Abstract:

  In this work, ZIF-67 is self-grown on the NiCo layered double hydroxide (NiCo-LDH) nanosheets-modified Ni foam (NF) surface. Its derivative, the hierarchically structured Co3O4/NiCo2O4/Ni foam (CO/NCO/NF) composite, is successfully fabricated by the oxidation of ZIF-67/NiCo-LDH/ NF, which exhibits excellent electrocatalytic performance. When assessed as an electrode for oxygen evolution reaction (OER), the CO/NCO/NF electrode shows low overpotentials of 320 and 407 mV at 10 and 50 mA cm−2, re…
